Doing lots of C interfacing lately I wonder if there is a way to create 
a D function with C calling convention but D mangeling. I need this to 
place C callbacks onto functions inside D templates. Putting extern(C) 
before it does not work in this case. As extern(C) will also enforce C 
mangling I get lots of duplicate symbol errors from the linker. I know 
that I can work around this using mixin(string) but I wonder if there is 
a other solution to the problem.

Yes it would, but then I would have to define some mangling for myself.

You can do something like this:

void foo ();

extern (C) pragma(mangle, foo.mangleof) void foo () { }

I'm pretty sure you remove the duplication with a mixin.
