--- Comment #2 from moonlightsentinel at disroot.org ---
Slightly reduced:

@safe:

auto foo(DG)(DG dg, int p) {
    return () => dg(p);
}

auto bla(int i) {
    return foo((int p)=>i*p, 66);
}

void main() {
    assert(bla(5)() == 330);
}

=====================================

Only requires -dip1000 which probably hints at invalid scope inference.
