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.
