Summary: incompatible change of string type name
Initial Comment:
In Python 2.1 and earlier, type("").__name__ was
"string". In 2.2a1, it is "str". This change breaks
the xml.marshal package of PyXML, which uses the type
name to generate a method m_string. Since there is no
m_str method implemented, running the marshaller
under 2.2 fails.

Note that the name "long int" also changed to "long". The
std repr.py was affected by this (and by string->str) too.
It was no bother to change it in repr.py, I expect the
point is more (a) possibly silent breakage (repr.py didn't
know it was broken), and (b) writing code that works under
all versions of Python.
WRT the latter, I bet Martin would be done if he just adds a
m_str = m_string
line to the affected class(es).

Hm. If I change the type's name back to 'string', the
built-in name for it has to be 'string' (otherwise some part
of marshal or pickle won't work). But I had hoped to use the
'string' built-in name for the base class of str and
unicode.
Is it terribly inconvenient to have to rename the m_string
function to m_str?
