If you just want line-in / line-out support, honestly, I could hack that
into ChucK in a few minutes this afternoon.  The problem isn't so much
getting stuff into and out of files, it's doing things with it once
you've got it.  ChucK doesn't have any significant string manipulation
functions.  You could use sort of a poor-man's delimiter by using one
data field per line and Std.atoi(), perhaps.

Even more interesting from my perspective would be the ability to
serialize ordinals (and perhaps later objects) directly to files, but
that's a bit more work.
