Comment #5 on issue 1562 by asmeurer: Have trigsimp apply factor and Poly.cancel() to sin's and cos's http://code.google.com/p/sympy/issues/detail?id=1562
I do not have Poly() instances in my solution (I understand that Poly() is mainly for efficient processing). I have RootOf instances, which I use to represent non-explicit roots. Basic.has() recurses through the args of everything, and a Poly() instance is in the args of Basic. Not only is my .has() code failing, but so does re(RootOf), which I would also like to use. Unlike Poly(), I think we should make RootOf to be more of a user class, as well as more general (not just for polynomials).
