I will review it tomorrow morning.

It could be useful sometime, but it is far from urgent.

Likewise, but even less urgent.

Sometimes, when converting a signed int to e.g. hex, one wants effectively
uint_to_hex(uint.cast_from_int(N)), and sometimes one wants uint_to_hex(
uint.cast_from_int(int.abs(N))) with possibly a minus sign in front of it.
People who want the former can easily write it themselves; the latter could
use a trivial library function.
