Bugs are a major theme on this list.  As far as I know, Parenscript lacks unit tests that run the compiled Javascript code. Is that still correct?  Perhaps it is time to introduce this feature?  There are a few options here:

- cl-javascript is a pure lisp implementation of ECMAScript, and it actually works for most normal language cases
- cl-spidermonkey uses the FFI to interact with Mozilla's JS engine
- v8, either through the FFI or a simple command line

This should allow the project to test much more rigorously than the current kinda kludgy test framework.

As a reference, I currently do this in PSOS: https://github.com/gonzojive/paren-psos/blob/master/test/test-package.lisp

It appears as though there might be a gap in the lexical scoping
implementation in the compiler:

(ps (lambda (x)
     (let ((x 1))
       (foo x))
     (incf x)))
=>
"function (x) {
   var x = 1;
   foo(x);
   return ++x;
};"

vs.

(ps (let ((x 10))
     (let ((x 1))
       (foo x))
     (incf x)))

"var x = 10;
var x33 = 1;
foo(x33);
++x;"

Although function parameters have their own lexical bindings,
the environment still needs to be informed of those bindings
so that LET forms in the function body can rename any conflicts.
