Is this really more natural or more readable? Hmmm.
For this type of situation, my preference would be:
class spam(object):
def __call__(self, x, y, z):
try:
mongo = self.mongo
except AttributeError:
mongo = self.mongo = heavy_lifting_at_runtime()
return frobnicate(x, y, z, mongo)
spam = spam()
No extra objects, out-of-place underscores, etc.
