digitalmars.D.learn - template definitions spanning modules.

- Nicolas Sicard (3/27) Aug 27 2013 It's a known bug:
Hi Consider the following code module A; void xx(T:int)(T t) { .. } void xx(T:float)(T t) { .. } module B; import A; void xx(T:string)(T t) { .. } void main() { xx!(int)(4); xx(4.5); xx("abc"); } The compiler won't let me do this. It will complain that xx!(int)(4) cannot be instantiated with xx(T:string). If I move xx(T:string) into its own module, the compiler complains about ambiguity. If I put them all in the same module, it works fine. I read about overload sets in the docs and tried the "alias A.xx xx" suggestion, but the compiler didn't like that either. Is there any way I can make this work without having to put them all in the same module? Thanks in advance. Jason.
