Sort of. It's mapped to PyObject_RichCompare(), which takes two arbitrary
objects and compares them.

http://docs.python.org/c-api/object.html

The C-API does this as the first object may not support the required
operation, in which case the operands will end up being reversed and passed
to the second object.

I just noticed that this isn't in the FAQ in our Wiki. It's definitely
worth going there.
