The namespace use is indeed problematic.  It needs a serious cleanup.
The (defvar this nil) is *really* nasty, since the unsuspecting user may
want to do

  (let ((this ...) (that ...))
    (lambda (x) (...this...that...)))

and be surprised to discover that his closure did not close over `this'
because it's a special (i.e. dynamically bound) variable.
