//                                                                            //
// The goal of matching is to compare a function call's arguments and any     //
// explicitly provided template types in the program source against an        //
// overload declaration in this file, and determine if the call satisfies     //
// the form and type constraints of the overload. If the call matches an      //
// overload, then the overload is added to the list of 'overload candidates'  //
// used for overload resolution (described below).                            //
//                                                                            //
// Prior to matching an overload, all template types are undefined.           //
//                                                                            //
// Template types are first defined with the type of the leftmost argument    //
// that matches against that template type name. Subsequent arguments that    //
// attempt to match against the template type name will either reject the     //
// overload or refine the template, in one of 3 ways:                         //
// (a) Fail to match, causing the overload to be immediately rejected.        //
// (b) Match the existing template type, either exactly or via implicit       //
//     conversion, and overload resolution continues.                         //
// (c) Match via implicit conversion of the currently defined template type   //
//     to the argument type. In this situation, the template type is refined  //
//     with the more constrained argument type, and overload resolution       //
//     continues.                                                             //
//                                                                            //

//                  (declared above)                                          //
//    <T: scalar> - declares the template type T, with the constraint that T  //
//                  must match one of 'f32', 'i32', 'u32' or 'bool'.          //
//                                                                            //
// The process for resolving this overload is as follows:                     //
//                                                                            //
//   (1) The overload resolver begins by attempting to match the argument     //
//       types from left to right.                                            //
//       The first parameter type is compared against the argument type T.    //
//       As the template type T has not been defined yet, T is defined as the //
//       type of the first argument.                                          //
//       There's no verification that the T type is a scalar at this stage.   //
//   (2) The second parameter is then compared against the second argument.   //
//       As the template type T is now defined the argument type is compared  //
//       against the value of the defined type of T. Depending on the         //
//       comparison of the argument type to the template type, either the     //
//       actions of (a), (b) or (c) from above will occur.                    //
//   (3) If all the parameters matched, constraints on the template types     //
//       need to be checked next. If the defined type does not match the      //
//       'match' constraint, then the overload is no longer considered.       //
//                                                                            //
// This algorithm for matching a single overload is less general than the     //
// algorithm described in the WGSL spec.  But it makes the same decisions     //
// because the overloads defined by WGSL are monotonic in the sense that once //
// a template parameter has been refined, there is never a need to backtrack  //
// and un-refine it to match a later argument.                                //
//                                                                            //
// The algorithm for matching template numbers is similar to matching         //
// template types, except numbers need to exactly match across all uses -     //
// there is no implicit conversion. Template numbers may match integer        //
// numbers or enumerators.                                                    //
//                                                                            //
//                                                                            //
// Overload resolution for candidate overloads                                //
// -------------------------------------------                                //
//                                                                            //
// If multiple candidate overloads match a given set of arguments, then a     //
// final overload resolution pass needs to be performed. The arguments and    //
// overload parameter types for each candidate overload are compared,         //
// following the algorithm described at:                                      //
//   https://www.w3.org/TR/WGSL/#overload-resolution-section                  //
//                                                                            //
// If the candidate list contains a single entry, then that single candidate  //
// is picked, and no overload resolution needs to be performed.               //
//                                                                            //
// If the candidate list is empty, then the call fails to resolve and an      //
// error diagnostic is raised.                                                //
//                                                                            //
