Although probably 2/3 of the implementation of Python deal with the type/object
implementations, from a using-the-language point of view the syntax probably
contributes more obviously to the observed "simplicity" of Python.
But the term "meta object protocol" seems to point much more into
the direction of types/objects as Michael suggests and here Python
has a lot to offer. Is there some free material on MOP somewhere?
FWIW, in the next pypy-sprint we'll probably try to deconstruct the python-syntax
and its resulting compilation and execution into several aspects. Maybe
we should term this effort meta language protocol :-)
