An excerpt from bpo-31369: re.RegexFlag and `__all__`
GvR: ----
One thing I discovered when developing this example: there doesn't seem to be a flag to represent 0 (zero), i.e. "no flags". And foo(0) is a type error (even though it works fine at runtime).
Which raises the question: Do we want to have a standard name for stdlib Flags when no flags are set?
What should we call it?
- NONE
- ZERO
- EMPTY
- ???
Definitely NONE. At some point I might even add it to the regex module! :-)
Not to confuse with None, which will not be equal to NONE. Hmm... Perhaps NONE_SET or ALL_UNSET? (also, why the ALL_CAPS?) Regards Antoine.
