replace the check that the inputs are Integers with a coercion of the
inputs into Integers? Once I coerce the elements the check is redundant,
as either it raises an error in and of itself (say, if it was passed a
string it will raise a TypeError), or will fix the problem.
I think I would prefer the input of type {{{int}}} to be coerced into
{{{Integer}}}, and throw an error if it's neither {{{int}}} nor
{{{Integer}}}. The reason is that one could potentially try to apply this
function to different from {{{ZZ}}} rings, with strange results, if one
just blindly coerces stuff into {{{Integer}}}.
