[PYTHON MATRIX-SIG] lists vs. tuples

[David Ascher]

Just a thought.

I believe that most existing python code, when returning collections,
return tuples.

The matrix code as implemented returns lists (e.g. shape).  Shape
strikes me as the kind of thing which might be better off being a tuple
than a list.  That way people doing:

 a = array(...)
 s = a.shape()
 s[0] = 3

would be stopped by the interpreter (I'm assuming this isn't working and
isn't likely to work).

Thoughts?
