If you're trying to fight back against Ruby's need for an explicit
receiver in assignment-style method calls, I think you've won a bit of
a Pyrrhic victory.  That looks like a bunch of assignments to local
variables; I wouldn't want to have to train my eye to find the word
"with" and then figure out that Ruby's normal assignment behavior was
temporarily suspended.  That's a heavy price to pay for avoiding a few
occurrences of the word 'self' (or 'some_obj', etc.).
