Hi Steven,
I recently put together a propagator/cell system using Clojure's
actors/watchers. The code for implementing a concurrent propagator
system actually came out to a little less than a single page. Take a
look at the following for the full implementation.

I'd recommend looking at how plt-scheme solved this problem (see [1]).
They actually defined alternative readers in which either prose or code

Hi,

I generally prefer to pass in a sequence rather than use a variable
number of arguments. The only time variable arguments are really useful
is in functions like map (or maybe +) in which you rarely use more than
one (or two) arguments and it would be a pain to wrap the last argument
in a list.

Hi Sunil,
This is already possible using `partial' function in clojure core, which
