Hiya, tried something yesterday, did a template like this:

template WinStart(alias userEntryPoint)
{
extern (Windows) WinMain(...)
{
..
results = userEntryPoint(...);
..
}
}

Which supposed to be used as a mixin, so I wouldn't have to manually write the ugly WinMain start for all programs.

Needless to say, this didn't work out, because extern, for somewhat obvious reasons, is ignored for templates (and, I think I tried it, for classes as well). What I don't understand is why the compiler lets this through without saying anything, and instead you get linking errors thrown at you.

Another thought was that maybe extern could be allowed for templates without arguments? As they would appear exactly the same everywhere they are used, no unique names are needed.

Any ideas how to do with the ugly WinMain? Or any comments on the rest?
