So can we look towards having things like "map" and "grep" be parallel

at least unordered) by default?
I don't think so. First and foremost, these functions produce ordered
results, that's the Perl semantics of it. Second, while we can for sure
do some multithreading, if we are waiting for IO or such, it's hard for
pure computations. Kicking off more threads has it's cost too and it's
only worth the effort, if the computation is taking a lot of time (or
CPU cycles). But that's a thing Parrot really doesn't know in advance.
That said, it's unlikely that autothreading w/o any user hints will
happen soon.
