Bug 14057 – [REG2.066] opSlice not working correctly with AliasThis

The below code should work, but doesn't: --- struct Wrapper { int[] subType; alias subType this; Wrapper opSlice(size_t, size_t) { return this; } } void main() { auto w = Wrapper(); Wrapper w2 = w[0 .. 1337]; } --- test.d(15): Error: cannot implicitly convert expression (w.subType[0..1337]) of type int[] to Wrapper --- The subtype with slice capabilities seems to get priority. This also happens if the subtype is another struct with opSlice.

It's a regression introduced in 2.066. https://github.com/D-Programming-Language/dmd/pull/4350
