Your Common Lisp example is a bit confusing.  Perhaps you're
referring to the difference between

	'(LAMBDA ...)

which creates a list that *can* be compiled or interpreted as a
function (with a null lexical environment), versus

	#'(LAMBDA ...)

which returns a closure (which may include variables from the
lexical environment in which it appears).
