I think used to work in dmd v2.063.2:



import std.algorithm: canFind;
void main() {
    enum Foo { x }
    [Foo.x].canFind(Foo.x);
}


With dmd 2.065alpha it gives:

...\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(3834): Error: template
instance std.traits.isSomeChar!(Foo) recursive expansion
