Unless one wants the intialization of mongo delayed in case spam is
never called, it can go in __init__ instead.
spam = Spam()
ham = spam(1, 2, 3)
I really like this. Thanks.
That's natural and readable.
From reading this thread, and the "(a==b) ? 'Yes' : 'No'" one, the
inescapable conclusion is that "readability" (like beauty) is very
much in the eye of the beholder, or, in this case, in the eye of
Guido.
