[issue31558] gc.freeze() - an API to mark objects as uncollectable

INADA Naoki added the comment: Should gc.freeze() do gc.collect() right before freezing? Or should we document `gc.collect(); gc.freeze();` idiom? I don't like `gc.freeze(collect=False)`. So if there is at least one use case of `gc.freeze()` without `gc.collect()`, I'm +1 on former (current pu

Nick Coghlan added the comment: As far as docs phrasing goes, it probably makes sense to frame it as "text" being the preferred argument name in 3.7+, with "universal_newlines" retained indefinitely as a compatibility preserving alias. After all, if that wasn't our intention, we wouldn't be a
