I don't think I quite understand what you mean by 'escape'? I mean,
generally speaking they get captured in the environment of the more
inner form (i.e. main has everything in its environment).
You could just as easily use something like defn- to regulate external/
internal-ness, I just happened to feel like using let in this
situation.
I think java has to do different stuff depending on whether something
is public or private. I think private is faster... I'm not a java guru
tho.

No i guess not. I used it in a couple of places I thought. Has been a
while since i looked at the code. :-)

Woo!
And you can make it faster yet! :-)
