New submission from Alexander Belopolsky <[EMAIL PROTECTED]>: Attached patch makes range objects precompute their length on creation. This speeds up indexing and len at the expense of a small increase in range object size. The main benefit, however is that unsupported length > sys.maxsize is detected early and confusing OverflowError from len(r) or r[i] is avoided.
