Assigning a variable to something can be anything else than a temporal alias.
A with statement makes clear that the alias is an alias and is local, and it
automatically clears the variable after the block code is used.
Python clutters the variable space with vars that are needed only on certain
places, and an alias doesn't has a scope.
Convenient alias are short names, and short names are limited in quantity. If
the space is cluttered with short alias, it opens risks for wrong utilization.
Its like writing a "for i" in a list comprehension and having to worry if "i"
was already used in another place..
As long as functions are kept reasonably short, which is a good idea
anyway, I don't really see any of that as a problem.
