Bug 1263 – Template function overload fails when overloading on both template and non-template class

struct A {} class B() {} class C {} void foo()(int) {} void foo()(A) {} void foo()(B!()) {} //void foo()(C) {} void main() { foo(5); // ok foo(A()); // ok foo(new B!()); // error if C overload available //foo(new C); // ok (with C overload available) } Uncommenting the C overload declaration produces this error: template t.foo() foo() matches more than one function template declaration, foo() and foo() This is apparently only triggered by the call to the B overload.

It appears to behave similarly with aliased template instantiations: class B() {} class C() {} alias C!() D; void foo()(B!()) {} void foo()(C!()) {} //void foo()(D) {} void main() { foo(new B!()); // error if D overload is used instead of C }

Fixed in 1.017.
