It's called by multi-dimensional opIndex (or opSlice and perhaps others?; can be very complicated :) ). import std.stdio; struct S { property size_t opDollar(size_t dim)() { writefln("Called for dimension %s", dim); return dim; } auto opIndex(A...)(A args) { return 42; } } void main() { auto s = S(); s[$, $]; } Called for dimension 0 Called for dimension 1 Ali
