It seems like a slippery slope. Sometimes you really don't care like when you're just hacking together a quick script. Isn't the "with" statement appropriate in these cases?

A hacked-together quick script might contain code like:

parse(open(bla).read())

Compared to this, "with" adds a new indentation level and a new variable, while breaking the flow of the code:

with open(bla) as foo: contents = foo.read() parse(contents)

People used to writing production code under stringent guidelines (introduced for good reason) will probably not be sympathetic to quick-hack usage patterns, but Python is used on both sides of the fence.
