[RFC] Using erlang constants/macros

[Jean Parpaillon]

The quaff project (https://github.com/qhool/quaff) allows importing erlang headers (.hrl files) into an elixir module.

macros are imported as module attributes and can be (optionally) exported as 0-arity functions.

I've updated the code (https://github.com/jeanparpaillon/quaff) to behave more like `import` statement and add missing features:

- added `only` and `except` options to whitelist / blacklist imported macros

- quaff can now parse deferred definitions. For instance

```

-define(FOO, ?BAR).

-define(BAR, 42).

```

which is valid in erlang but was raising error in upstream quaff.

Would you be interested in including this library in mainstream elixir ? It would complete the Record module for better erlang / elixir compatibility.

Best regards,

Jean Parpaillon

Hi Jean,

Unless there is something broken in our interface with records, I believe this is perfectly fine as a library. It is not a very common use case and users can reach out to your library if they need it. :)

Thanks for pinging!
