pprint's Issues

Decoder decodes custom types with no fields as foreign types on the Erlang target

Basically, instead of a custom type with no fields such as Foo being decoded as TCustom("Foo", []) on the erl target, it is decoded as TForeign("Foo"). This must be due to the way custom types are represented in Gleam under the hood. Don't know much about this, so calling in the erl master @giacomocavalieri.

Can't install
