I don't think Hayleigh was trying to gatekeep, just noting that some developers prefer features that Gleam intentionally omits.

As for the @external annotations, I think you're both right to a degree. Perhaps we can all agree to say: Gleam can use most libraries from Erlang/Elixir, but requires some minimal type-annotated FFI bindings to do so (otherwise it couldn't claim to be a type-safe language).
