Comment(by tdupu):
There is a smarter way to implement this I think. When computing something
like
{{
(f*g).residue()
}}
you really don't want to multiply out both f and g and then take the
residue but rather sum over the coefficients which sum to -1. Is there a
way to do this and things like this with the preparser?
