Jeff Dalton says:

   I would not say Pop got it right, because (1) variables in Pop have
   dynamic scope and (2) closures have to have an explicit annotation
   listing the variables to close over [cf FUNCTION in Lisp 1.5].  I
   regard these as more significant defects.

Older Pop didn't get it right, tis true. However, current versions of Pop11
(Aaron can supply dates - lest's just say for at least a couple of years)
have had full lexical scoping - ie non-dynamic scope and implicit closures.

I, too, would regard their absence as a significant defect. Conversely, I
regard the explict presence of partial application ("consclosure") as a +ve 
feature.
