akira added the comment:
If `len()` signature can't be changed to return Python int objects (unlimited)
then the OverflowError may contain the actual `.length`
property instead (based on msg66459 by Antoine Pitrou)
operator.length():
def length(sized):
"""Return the true (possibly large) length of `sized` object.
It is equivalent to len(sized) if len doesn't raise
OverflowError i.e., if the length is less than sys.maxsize on
CPython; otherwise return OverflowError.length attribute
"""
try:
return len(sized)
except OverflowError as e:
return e.length
