Yes, that’s let assert on pattern matches. We’ve briefly evaluated Gleam (but I only very shortly) and result was that we cannot port existing code any way and integration would be very difficult (especially given missing macros).

I do, however agree with you on macros and code generations. My hand in Rust is macro heavy (I dislike boilerplate) but in Go I learned to appreciate codegen utilities and it might be the way to go.

The topic itself is interesting, because I’ve been doing „business logic in types” and it’s impossible to pull of without invoking so much magic that keyboard starts to emit indigo and that puts Gleam in akward place because when we are at that place maybe it’s easier to write code generation with Prolog/Cue but instead of putting another layer just settle with Erlang/BEAM assembly.

But my problems are more in domain of „what happens when during daylight saving shift I receive an out of order message that should be included in generated raport of order fashion and one of node died at that point”.
