Bug 109 – incorrect name mangling for template value arguments

template T (long x){ void T(){ } } mixin T!(1); mixin T!(1u); mixin T!(1L); mixin T!(1Lu); generated symbols: _D1a9__T1TVi1Z1TFZv _D1a9__T1TVk1Z1TFZv _D1a9__T1TVl1Z1TFZv _D1a9__T1TVm1Z1TFZv shouldn't all manglings be: _D1a9__T1TVl1Z1TFZv While the current mangling doesn't cause bugs in pure D code it could lead to nasty problems if D and non-D code are combinded.

This is actually how it is intended to work. The idea is to create the name based on what the arguments to the template are *before* coercion to the various specializations and types of the template declaration. This enables the user to add specializations to a template without having to rebuild libraries that also use that template. It won't generate problems with non-D code, as non-D code won't be instantiating D templates.
