| 380188 [jrmair gmail] No, it *does* create a new lexical scope -- did you test it ? :)
| 380210 [gwtmp01 mac.] I think it was my sloppy terminology that was confusing.  My intent was that the phrase 'lexical scope' would refer to the scope that was relevant to constant and class variable resolution.  As you've pointed out, that phrase just is not specific enough as there is a lexical scope created for local variables by the singleton class notation (and blocks).  So there are at least two different types of lexical scopes that affect name resolution of variables and constants.  I'm not sure if there is any standard terminology used to differentiate them.  Perhaps that is part of the confusion.
