digitalmars.D.learn - Overload sets and templates

This works:

------------------------------
void foo(T)(T t) if(is(T==char)) {}
void foo(T)(T t) if(is(T==int )) {}

void main() { foo(1); }
------------------------------

But if I move the "int" version to a different module, and try to alias 
it into the current module's overload set (like I can with non-templated 
functions), I just get an error that the "char" version of foo conflicts 
with the alias:

------------------------------
module a;
import b;

alias foo = b.foo;
void foo(T)(T t) if(is(T==char)) {}

void main() { foo(1); }
------------------------------
module b;
void foo(T)(T t) if(is(T==int)) {}
------------------------------

What's up with that? Is there a way to do it?

What you are trying to do should work. I.e. this is a compiler bug.
