One discussion is about inclusion in core (settled), and a different discussion is about semantics.
The point of invert is: when you as a programmer know the mapping is a bijection, and you need boths directions, you know invert is well-defined and can use it (present in some languages). If the mapping is not a bijection, you as a programmer know invert probably doesn’t make sense, it is undefined behaviour, or whatever. The former has uses cases (I have used it), the latter probably not or rare. -- Sent from Gmail Mobile -- You received this message because you are subscribed to the Google Groups "elixir-lang-core" group.
