It’s discouraged to pass around structs of functions to replicate type classes in Gleam. Instead the preference is to not type class style patterns in your projects, favouring a concrete style instead.

Does that mean pass every needed function as a parameter? Or just don’t write generic functionality?
Yes, one would use higher order functions, as is common in Erlang, Elixir, OCaml, Elm, etc.
At least half of those languages (Elixir and OCaml) have some sort of mechanism for ad hoc polymorphism (elixir has behaviors and protocols, OCaml has higher order modules) so I feel like the comparison doesn't work that well personally
