We should have it, but it should be a namespace-scope function, not a
method. len(some_list) and len(some_tuple) should work equally well.
There are actually a whole suite of these functions which ought to be
in the library, added to namespace boost::python::api (see
boost/python/object_protocol.hpp for some examples). Patches are
welcome, if they include user documentation and tests!
