Bug 13783 – Function overload with rvalue `inout` parameter not selected when `enum` parameter implicitly converted to its base type

This code should work fine: --- enum E { a } inout(int) f(inout(int) t) { return t; } ref inout(int) f(ref inout(int) t) { return t; } void main() { const E e; f(e); // line 9 } --- main.d(9): Error: constant 0 is not an lvalue --- May be related to Issue 12068.

Fixing 13783 will disallow the accepts-invalid bug. https://github.com/D-Programming-Language/phobos/commit/ca2171d49ce58162e7489061588a2e2d3d5b1d8c Merge pull request #2773 from 9rnsr/fix13783 Supplemental fix for issue 13783 in std.parallelism

For the function `auto f(ref T);`, an lvalue of `enum E : T` should not match. https://github.com/D-Programming-Language/dmd/commit/b27e1501a970c158f78874bb6f71355b7d6f7c5a Merge pull request #4177 from 9rnsr/fix13783 Issue 13783 - Function overload with rvalue `inout` parameter not selected when `enum` parameter implicitly converted to its base type
