https://issues.dlang.org/show_bug.cgi?id=21752 Issue ID: 21752 Summary: Template constraint breaks overload resolution Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: moonlightsentinel disroot.org A template constraint for a nested template breaks overload resolution in the following example (even though the constraint is satisfied). Commenting the constraint or moving it into a `static assert` fixes the problem. ------------------------------------------------------------ void foo(A)(A a) {} template foo() { void foo()() if (true) // Comment this constraint to make it pass {} } void main() { foo!()(); } ------------------------------------------------------------ The original code used nested templates to create two variadic parameters but those are not required to trigger this bug. --
