I observed this failure only in the Windows platform (Python 2.7.1), but
didn't in linux for Python 2.4.4, 2.4.6, 2.5.5, 2.6.5, 2.6.6, 2.7.1.
Possible it is related wit

Ok, this patch changes laguerre_l to generate polynomials in *unexpanded*
form. I think it's a step back, as now you always need to call expand().
Let's figure ou

Mateusz, should the laguerre_l() return expanded or unexpanded polynomials?
It makes better sense to me to return expanded polynomials.
In any case, I have fixed

To clear for my self, I have a question why does `expand()`'s behavior
differs on windows and linux system? Or it is related with orthopoly?
Should the appropriate test
