I prefer Matrix_i. I would really prefer something explicit like IntegerMatrix,
CharacterMatrix, etc, with Matrix reserved as euphemism for RealMatrix or
as a "smart" constructor as I discussed before.
It turns out you just don't use this kind of constructor much anyway,
as most matrices are produced by array functions/operators, not literal lists.
In the particular case of python there is some history having to do with using
characters to represent popular types, so the present choice is reasonable
and I don't feel strongly about this.

abbreviation it is."
