Please feel very free to use any identifier with a _notmuch prefix. And really, feel free to use just about any underscore-prefixed identifier that you want that doesn't clash with anything on your system. Then if we do identify an actual clash somewhere then we can fix it. I think it was stupid of Posix to steal _ and a reserved prefix, and I really don't have a problem ignoring that. This is like I described in a recent mail---trying to prevent all portability problems just isn't worth the effort. It's much easier to fix problems that actually occur in practice. =2DCarl --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iD8DBQFLUMzd6JDdNq8qSWgRAmh/AJ9oRSoe9/H32Wu8JqEMv0HBm55OnwCfT0N7 z5WdgEgWvZkXMW2VL/phfX4= =Rr1C -----END PGP SIGNATURE----- --=-=-=--
