digitalmars.D.bugs - [Issue 16165] New: Better error message for mismatched function

https://issues.dlang.org/show_bug.cgi?id=16165

          Issue ID: 16165
           Summary: Better error message for mismatched function argument
                    types
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: johnnymarler gmail.com

Currently when a function call has mismatched argument types from the function
definition, an error message like this will get printed when compiling with
dmd:

Error: function myfunction(...) is not callable using argument types (...)

When a function has more than a couple arguments (like most Windows functions),
it can take a bit of effort to figure out which argument is incorrect. Adding
extra information like this: "Cannot convert argument 3 'message' from int to
string" or "you've called myfunction with 10 arguments but it only has 9",
would help developers save time trying to figure out what actually went wrong.
