If you error from Erlang or Elixir you will get the error as those languages construct them, even if you call that code from Gleam. The Gleam build tool attempts to print them more nicely than Erlang does by default, but it cannot add additional information to them. Gleam runtime errors have more information attached to them. In practice runtime errors in Gleam are rare. The one place you'll likely have to deal with poor Erlang errors is if you are writing Erlang code to create Gleam bindings to an existing Erlang library.
