For inverting in the original parent ("internally"), the name
"m.inverse_of_unit()" is used widely in Sage, e.g. in integer rings,
polynomial rings, p-adic rings, etc. The name "m._invert_unit()" seems to
be used only for matrices. I now understand the "unit" in the name for
differentiating fro

On the other hand, "inverse" or "invert" implies that m is(should be) a
unit. Then "unit" in the name seems redundant...

I've always wondered why we didn't use GH.

option. I'm not sure if trac is the best place to put it, but I think one

Do you have any suggestion for the name of a method for *internal*
inversion in a multiplicative monoid (e.g. ring). Currently I know of
sage: (-1).inverse_of_unit()
-1
sage: m = matrix(2, [2,1,1,1])
sage: m._invert_unit()
[ 1 -1]
[-1 2]
I would like to standardize the name in order
