Bug 12904 – Wrong-code for some slice to slice assignments when using `opDollar`

This code should run fine: --- struct S { size_t opDollar(size_t dim)() // never called but should { return 7; } int opSlice(size_t dim)(size_t, size_t to) { assert(to == 7); // fails return 1; } int opIndex(int, int) { return 1; } void opSliceAssign(int) { } // This functions existence prevents `opDollar` from being called: void opIndexAssign(U, A...)(U value, A args) { static assert(0); } } void main() { S s; // `s[0..$, 0..$]` causes ICE Issue 12902 s[] = s[0..$, 1]; } --- Probably has the same root as Issue 12902.
