Nested scopes were put into the language for function definitions, at 
least. Back in around 2.0, I believe, though that's lost in the mists of 
time for me as it's not a feature I use.

I suspect, in fact, that those nested scopes have caused more trouble 
that they're worth, and continue to do so. Be that as it may, I don't 
think there's ever been any attempt to introduce scoping blocks into the 
language.

Any ideas how you'd like it done?
