I get some DateTime strings I wanted to parse.
DateTime looks quite nice for such things but somehow it can produce the datetime strings in the exact same format but it can not parse them.
I was expecting it can at least parse what it can produce
datetime = DateTime.utc_now
datetime_basic_string = DateTime.to_iso8601(datetime, :basic)
DateTime.from_iso8601(datetime_basic_string)
#sadly results in {:error, :invalid_format}

Like the documentation for
DateTime.from_iso8601/2says (emphasis mine),It currently does not even try to parse the “basic” version.

I do not say the documentation does not match the behaviour. I say the behaviour is unexpected and does not make sense.
If it can produce it parsing should also be possible.
Its a missing feature if you want it that way

True, it would be more consistent if it would work both ways (:basic and :extended).
Well, you should do the PR then. As your change makes sense and does not harm the existing API, should be accepted!
