Sorry, I should have been a little more specific.  Of course: APL
already provides an excellent environment for program development, but
this is due mainly to the concept of interpretation as such.  As we are 
working on visualizing APL concepts to aid learning APL, I would be 
interested in more specific pointers to the packages mentioned.

E.g., has no-one felt the need to single-step through the execution of
an APL function, watching the values of variables change (in an extra
window, for instance)?  Personally, I find the Trace- and
Stop-primitives just too primitive.
