[issue18652] Add a “first” function to the stdlib

[Hynek Schlawack]

Hynek Schlawack added the comment:

Ah ok sorry. Anyhow, it’s just a very common idiom that should be easy and readable.

As said, I’m not married to any names at all and would happily add a compatibility package to PyPI with the new names/parameters.
