How often do you expect someone to be looking at code where a trunc()
method is being called and the variable could plausibly be both a
number or something else?  (a Google Code search for "def trunc(self)"
lang:python returns 1 hit)

How does the that additional value weigh against the cost of adding
another builtin and trying to explain trunc() versus int() to new
users?
