https://issues.dlang.org/show_bug.cgi?id=21354 Issue ID: 21354 Summary: 'cannot deduce function' errors print enum template params in an ugly way Product: D Version: D2 Hardware: All OS: All Status: NEW Keywords: diagnostic Severity: enhancement Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: elpenguino+D gmail.com ``` enum Test { a, b } void test(Test t : Test.a)() {} void main() { test!(Test.b)(); } ``` This code, on DMD 2.094.1 and earlier, prints the error `Error: template instance test!(cast(Test)1) does not match template declaration test(Test t : (Test).a)()`. This is also true when there are multiple matching candidates. dmd should print `Test.b` rather than `cast(Test)1`. --
