           Summary: Cannot pull a function template into an overload set
           Product: D
           Version: unspecified
          Platform: All

            Status: NEW
          Severity: major
          Priority: P2

Works with regular functions, but not function templates:

------------------------------
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)) {}
------------------------------ 

Error: template a.foo(T)(T t) if (is(T == char)) conflicts with alias a.foo at
a.d(4)

FWIW, The problem does not appear to be related to the "if(...)" constraints,
because using these foo's has the same problem:

void foo(T)(int[T] t) {}
void foo(T)(T[] t) {}

Workaround:

------------------------------
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)) {}
------------------------------
