Function dmd.func.FuncDeclaration.overloadModMatch

Find function in overload list that matches to the 'this' modifier. There's four result types.

final FuncDeclaration overloadModMatch (
  ref const(Loc) loc,
  Type tthis,
  ref bool hasOverloads
);

1. If the 'tthis' matches only one candidate, it's an "exact match". Returns the function and 'hasOverloads' is set to false. eg. If 'tthis" is mutable and there's only one mutable method. 2. If there's two or more match candidates, but a candidate function will be a "better match". Returns the better match function but 'hasOverloads' is set to true. eg. If 'tthis' is mutable, and there's both mutable and const methods, the mutable method will be a better match. 3. If there's two or more match candidates, but there's no better match, Returns null and 'hasOverloads' is set to true to represent "ambiguous match". eg. If 'tthis' is mutable, and there's two or more mutable methods. 4. If there's no candidates, it's "no match" and returns null with error report. e.g. If 'tthis' is const but there's no const methods.
