No, this does foo!(args[0]), foo!(args[1])...).

He wants a runtime call to each arg wrapped with foo.

One could do:

auto wrapFoo(alias arg)() { return foo(arg); }

and then f(staticMap!(wrapFoo, args));

But this means you have an additional function call (which could of 
course be inlined). It is a viable solution though (tested, and it does 
work).
