- Convert Erlang tokenizer/parser errors to SyntaxError, format exceptions
- Raise TokenMissingError for incomplete input
- Use the same snippet code as Elixir does

I think we should encapsulate this in a function? Something like syntax_error(SyntaxError, description, code, location, env)? Then we can reuse it from different places. :)

Check the latest commit, like that?

Looks great! Ideally we would show them as Erlang errors (as in the Erlang shell) but I think this is a great first step. :) |

@filmor awesome, can you also add an evaluator test for those errors? :) |
