Yes, I definitely agree! We should have done this from the start. I
think Uffe Wiger suggested this some time ago also. [Right, I see
now that he did, I also commented on that one:
It's pretty trivial to fix in erl_lint.erl.
Of course, you'd have to make sure that the compiled behaviour module
is in the compiler's path, but I think that should be up to the
developer (e.g. by using .erlang).
