Now _that_ is possible and could well be helpful.

For that matter, I invite you to consider this example in pure ASCII:

1> c(snark).
{ok,snark}

where in the shell

m% cat snark.erl
-module(snark).
-export([f/0]).
f() -> [ '', '', '', '', '', '', '', '' ].

but in my text editor,

f() -> [ '^@', '^A', '^B', '^C', '^D', '^E', '^F', '^G' ].

It would probably be a Good Thing if Erlang gave at least a warning
about control characters in atom, string, or character literals
written without using \ .

I'd write this up as an EEP if EEPS didn't have to be in Markdown these days.
