Is there anyone with experience on a large Elixir/Phoenix code base? Is the lack of static type system a problem?
I find that a large Elixir codebase is easier to work with than a larger Ruby or JavaScript codebase, but it still has the same difficulties to some degree.
If you're a typing fan as I am, and you are interested in the BEAM then you may want to check out [Gleam, a sibling language of Elixir](https://github.com/gleam-lang/gleam/) which has an Elm/OCaml/F# style static type system. It provides many of the strengths of Elixir but with that statically typed programming style which you may prefer.
