[racket] CoreMIDI bindings

Yeah, I will if I flesh this out and put it on planet. That was more
just to make sure it works (didn't even mean to include it). Thanks
for the tip, though, rackunit looks helpful and relatively familiar in
design.

re: let/for forms -- I guess I'm just not sure what's the favored form
for a given situation. I'm impressed by how expressive operations like
these can be in scheme, but sometimes this is a hindrance as well as a
help as I'm never sure which is the "right" one to use.

In contrast to other languages where namespacing is used heavily (sometimes even to a fault), it seems that many scheme libraries are quite flat. Is this simply left up to the user to manage, or does the module system take care of this, or is there something else I'm missing altogether? Forgive the naïveté if this should be clear to
