Why not leave sq_length as is, but have len() bypass it and call
.__len__() directly?  C code is likely allocating memory for whatever
length it's given, so a sq_length overflow just makes it fail earlier,
whereas python code could be more creative (such as printing the
length of an on-disk container.)

The problem with the indexing API also calling sq_length is moot since
you've decided to remove it from range.
