I don't know, I learned on Pascal way back when and it did the same thing 
(basically), although it did allow you to alter the value of the variable 
from the enclosing scope, so this approach makes sense to me (in fact, when I 
moved to C, I missed nested function scoping as it can provide a nice 
organizational method).  I suppose this is simply one of those issues that is 
mostly a matter of preference, so I simply disagree.
