It's generally bad form in Python to say, for example

   d.has_key(foo)

rather than

   foo in d

The former assumes the "has_key" method (commonly there when d is a
dictionary) and so doesn't work for other containers like lists, tuples,
sets.

In short, if you're going to do addition, all you should be worried
about is whether the operands support the addition protocol. You
shouldn't care about (and shouldn't definitely not check for) the types
of the operands which is what, from Arul's comment, the VCS module seems
to be doing.
