Please don't post things as bugs unless you're reasonably sure they're
bugs.  This is a difference between R and S-PLUS.

It's well documented that R and S-PLUS have different scoping rules
(see 3.3.1"Lexical Scoping" in the FAQ), but I don't think that's
coming into play here.  

What we have is a reference to a global variable that modifies it.
For some reason S-PLUS doesn't allow that, but R does.  Why do you
think it's a bug in R?
