[Pyrex] Small addition to the FAQ

[Conrad Steenberg]

Hi

Since I struggled a little with this last night, here is a proposed FAQ
addition - basically a corollary to the last FAQ entry on 
http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/version/Doc/FAQ.html

-----
Q: Pyrex says my extension type object has no method 'eat':

cdef class Vegetables:
  cdef int rhubarb

  cdef eat(self):
    munch(self.rhubarb)

A: The method is not declared as a Python object and is not
automatically added to the class attribute list. See
http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/version/Doc/overview.html#Footnote2

To make the method callable from outside the class definition, define
the method using 'def' instead of 'cdef'.

Conversely, this scope rule may be used to hide methods from outside
code when needed.
-----

Is this correct?

Btw, Pyrex has already saved me days, if not weeks, of coding time. I
used it in bindings for an AVL tree library and SAMBA's tdb, both of
which are in production in a Python-based web service framework
(clarens.sf.net). Thanks!

Cheers

Conrad
