Walter, is it possible to add user-defined attributes to the language - something that would conform to this in C:

    #ifdef DLL
        #define MYEXPORT __stdcall _export
    #else
        #define MYEXPORT __cdecl
    #endif
    ...
    MYEXPORT void foo() { }

It could look like this:

    version (DLL)
        attribute MyExport = extern(Windows) export;
    else
        attribute MyExport = extern(D);
    ...
    attribute(MyExport) void foo() { }

Could be helpful in writing projects that can be either
static libs or DLLs, as well as porting such (zlib!) to
D.

Why would functions in a DLL need a different calling convention?

Because it might be called from languages other than D.

You can always just leave it in the C or Windows calling convention.
