That would certainly raise many issues. For example, this type would
certainly not have a unary minus... and if a negative result is found in
intermediate calculations, C_E should be raised.

Totally different arithmetic => a new kind of integer type. Just for the
sake of a single (albeit important sometimes) use case.
