[New-bugs-announce] [issue44939] proposal: add support for regex in Literal type hint

[Leon Mintz]

New submission from Leon Mintz <leon.mintz at gmail.com>:

Could typing.Literal (or analogous) accept a regex pattern to match against?

For example, if I want a duration string,

duration: str  # allowed syntax: 3s, 3m, 3h etc.

vs

duration: LiteralPattern['[0-9]+[smh]']
