Comment(by robertwb):
Finished reading expression.pyx, it looks good. Should this work:
{{{
sage: ((x+y)^9).polynomial(None, ring=ZZ['x']['y']).list()
------------------------------------------------------------
Traceback (most recent call last):
File "<ipython console>", line 1, in <module>
File "expression.pyx", line 3616, in
sage.symbolic.expression.Expression.polynomial
(sage/symbolic/expression.cpp:17320)

raise TypeError, "%s is not a variable of %s" %(v, ring)
TypeError: y is not a variable of Univariate Polynomial Ring in y over
Univariate Polynomial Ring in x over Integer Ring
}}}
Also, there are a lot (too many IMHO) aliases for simplify_radical
{{{
radical_simplify = simplify_log = log_simplify = simplify_radical
simplify_exp = exp_simplify = simplify_radical
}}}
