Make "`aa[key]`" use the same runtime call as "`key in aa`". The runtime calls these were using were different, but with equivalent definitions. With `ldc -O3`, the following functions now all compile to the exact same code: {{{ int[int] y; void foo(int x) { if (x in y) { auto z = x in y; sink(*z); } } void bar(int x) { if (x in y) { sink(y[x]); } } void baz(int x) { if (auto p = x in y) { sink(*p); } } }}}

module scope_exit_foreach;

void bar(size_t);

long foo(ubyte[] arr) {
    scope(exit) {
        foreach (ref b; arr) {
            bar(b);
        }
    }
    if (arr.length == 3)
        return 0;
    return arr.length;
}
