Comment(by mderickx):
The "This code is quite general" comment did what it had to do. I put it
there in the hope that someone would come with a suggestion like you did.
I had the feeling that the dubble code could be removed in a nice and
general way, but I didn't know how. So by what you say I should just move
the code to a more general class and then it will also work for fraction
fields and polynomial rings (and possibly even more rings). What would be
this more general class and where to find it?
sage/rings/ring_element.py has only one line of code:
{{{
from sage.structure.element import !RingElement, is_RingElement
}}}
So should I add it to the RingElement class thats imported
from sage.structure.element?
