Good point. You do need to completely macroexpand the effective
or implicit (RUN macro generated) QUASIQUOTE form & subforms before
emitting any function calls, but that said, it *is* possible.[1]

    with something like Alexander Schmolck's code [and make sure
    that doesn't break something else!], but at least the simple
