He asked it be in the documentation, but didn't say it had to be
in the language specification.  There could conceivably be documentation
for the implementation.  Eg, the Jython documentation includes a (very
outdated) description of what's different between the C and Java
implementations of Python, at http://www.jython.org/docs/index.html .

So Andy Todd could be looking for such documentation.  Which doesn't
really exist.
