For some expressions, it is convient to introduce additional
variables to do the conversion. So to_poly invents new variables. If
you don't like these variables, you should be able to eliminate them with
Without the additional variables, I think to_poly would generate more
supurios solutions, I think.

Maybe this has been fixed in 5.15.0. Actually, I think some of the assume
aren't needed anymore.
