Most of this is pretty grotesque, but it works relatively well. I wanted
to come up with a way to make redirect stdout so that print would send
content to a scratch buffer. I set it up so that I could assign an
execution command to filetypes using autocmd. It executes that command on
the content, and then puts the output in the scratch buffer. if the
scratch buffer doesnt exist yet, it creates it. The way it finds the
scratch buffer is really kludgy, but I couldnt think of a better way.
The 'PyValOut' function is kind of neat. It takes the selected content in
the current buffer and evaluates it through the embedded interpreter and
dumps the content to the scratch buffer. I use this instead of interactive
mode a lot of the time. I use this stuff regularly for several languages
including ruby.

My CamlComment function is kind of funky, it puts ocaml comments around
the text of the current line, respecting starting whitespace. The
CamlRunAct function is a quick and dirty shortcut I use to control whether
I want the file to be run through the ocaml interpreter, or the compiler,
or something else entirely. I'll probably port all this to ruby as soon as
I get ruby/vim working, and figure out how to redirect stdout.
