sys.flags.gil should be a "sequence" attribute #122575
Description
Bug report
sys.flags is a PyStructSequence. PyStructSequence is similar to a named tuple, but it can have attributes that are not part of the sequence.
Currently, sys.flags.gil is not a "sequence" attribute:
>>> import sys
>>> sys.flags
sys.flags(debug=0, inspect=0, interactive=0, optimize=0, dont_write_bytecode=0, no_user_site=0, no_site=0, ignore_environment=0, verbose=0, bytes_warning=0, quiet=0, hash_randomization=1, isolated=0, dev_mode=False, utf8_mode=0, warn_default_encoding=0, safe_path=False, int_max_str_digits=4300)I think this was an oversight. We forgot to update the n_in_sequence field from 18 to 19 in gh-116338:
