Oh, sure, though I wouldn't worry too much about current Parrot "users"
being unable to handle such things -- for the most part it'll pick them up
correctly from the Configure defaults from the perl5 being used to build
Parrot. (If run as part of an automated smoke test, for example, we'll
possibly pick up all sorts of 32/64 permutations.)
However, you're right. The Configure mechanism ought to be able to
compile and run a small program. The interface for doing that ought to be
set up before too much effort is made splicing it in ad-hoc. Having
someone else do that hard work has been one of my main goals :-).
