What is the motivation? Is it just to reduce typing?

Being an ex-Pascal coder myself, I originally missed having a 
Pascal-like 'with' statement too. But now I'm not so sure it is needed.

I know this proposal (under the name 'with') has been discussed before, 
but I can't find a PEP for it... ah, here you go, it was in the FAQs:


C-# doesn't have one either:

I don't think there are any problems with a Pascal-style 'with' 
statement that couldn't be overcome, but I don't think the benefit is 
great enough to create a new keyword for it. Can you explain in more 
detail why this proposed feature is useful?
