Arbitrary-precision integers for static compilation.
The static compiler does not use unlimited-precision integers,
like Python normally does, because of their unbounded memory requirements.
Instead, it allows to choose a bit width (usually 32 or 64) at compile-time,
and all computations follow wrap-around semantics on overflow.
This class implements the same semantics on the host.
For example:
>>> a = int(1, width=64)
>>> b = int(3, width=64) + 2
>>> isinstance(a, int)
True
>>> isinstance(b, int)
True
>>> a + b
int(6, width=64)
