Bug 15120 – alias overload set combine error message

//modA.d auto foo(T)(T a){} //modB.d auto foo(T)(T a){} //modC.d import modB, modC; alias foo = modB.foo; alias foo = modC.foo; void main() { .foo(3.4f); } modA.d(7): Error: modA.foo called with argument types (float) matches both: modB.d(1): modB.foo!float.foo(float a) and: modC.d(1): modC.foo!float.foo(float a) which makes perfect sense. However, if we drop the . before foo, i.e. foo(3.4f); modA.d(7): Error: overload alias 'foo' is not a variable which is very odd.

It's fixed in git head as a part of issue 14858. *** This issue has been marked as a duplicate of issue 14858 ***
