Since we don't have these constructs, lowering would need to
explain what happens here.
Nitpick, but D has something very similar to that:
if(auto val = expr()) { ... }
it just depends on val implicitly casting to bool.
It's okay if the resulting code is ugly, it won't be
user-visible.
We do have to be careful about this - error messages sometimes
leak that ugly code out.
