Bug 16165 – Show expected number of function arguments on mismatch

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.
