As other solution, string mode may be replaced directly with callable

F.text.regexp(r"(\w+-\d+)", mode=re.findall).as_("issues"),

[JrooTJunior]

It can be completed without making it breaking.

For example you can set mode by default to None, when you set search as True just set mode to SEARCH and show deprecation warning, when search is False set mode to MATCH but when both parameters are set just raise an error that indicates you can't set both parameters.

.regexp(...) -> .regexp(..., mode=RegexpMode.MATCH)
.regexp(..., search=True) -> .regexp(..., mode=RegexpMode.SEARCH) + DeprecationWarning
.regexp(..., search=True, mode=RegexpMode.FETCHALL) -> Error

@JrooTJunior, okay, I'll take it.

What do you prefer enum params or callable?
If enum, in which file should I place it?

[JrooTJunior]

I'd like to use enum or literals instead of passing methods in due to instead of re methods can be passed any function
