It shouldn't be hard to create a clojure archetype actually, now that
clojures in the main repo, if I get a compiled version of my
clojure-maven-plugin in a public repository somewhere I could easily make an
archetype that combines the two, with a ready to run clojure project.

this is how you do it:
user=> (def a 0)
#'user/a
user=> (binding [a 1] (map #(+ % a) (range 5)))
(0 1 2 3 4)
user=> (binding [a 1] (let [a a] (map #(+ a %) (range 5
(1 2 3 4 5)

I haven't compared it directly to any other parsing libraries, but I'd

Java ones.
Currently, the optimizations that the library has is that it lazily

I'm trying to determine if there is a way to gain access to the
dynamic and lexical bindings tables at both run-time and compile-
time. In general this seems like a bad idea, but I'd like to be able
to modify the evaluation environment while performing compile-time
partial evaluation. Last night

Just nest multiple binding forms:

closures capture lexical scope, binding creates dynamic scope. lexical
scope is where a closure is defined, dynamic is when it is called.
because filter is lazy, the closure is called outside the dynamic
scope created by binding

I'm a little unclear on why this happens still.
#(= % a) is a closure, correct? My understanding is that this should
capture the environment when it is defined. Why does "the environment" not
include the current bindings?

filter is lazy, and your lazy seq is "leaking

In this case, I was expecting a list with 3 in it.
