``` void f() { struct X { auto opSlice(size_t a, size_t b) { return ""; } } auto x = X()[0 .. $]; } ``` The error is technically correct, but not exactly helpful. __dollar is an implementation detail that should not be exposed to the user. I would expect something more along the lines of "Error: no $ operator overload for type X".
