This is a good point, but it's not a fatal flaw of the proposals, just a good feature to add to them. I'm rather dubious about the namespace issue (as I intend to say later on), but I don't think that scoping is a problem for any of the proposals other than the high colonic -- and that proposal simply avoids the problem by requiring full qualification. FWIW dynamic scope is definitely useful in some cases, and we should make sure not to forget to examine techniques and implications of it for anything we decide. -- David _________________________________________ David Durand dgd@cs.bu.edu \ david@dynamicDiagrams.com Boston University Computer Science \ Sr. Analyst http://www.cs.bu.edu/students/grads/dgd/ \ Dynamic Diagrams --------------------------------------------\ http://dynamicDiagrams.com/ MAPA: mapping for the WWW \__________________________
