Indeed. It's a lot bigger than any machine that will exist in my lifetime
can hold.
int.bit_length() is stored as a system-native integer, e.g. 64-bit, rather
than recursively as a Python int. So the largest Python int is
'2**sys.maxsize` (e.g. '2**(2**63-1)'). I may possibly have an off-by-one
or off-by-power-of-two in there :-).
