I guess I've been a bit grumpy the past couple days and over-stated the "*absolutely* *necessary*" part above. It should have read "*necessary*", not "*absolutely* *necessary*". I'd just like us to question if it's necessary here. Is there a good enough way to do this without causing the breakage? I sorta liked Warren's question. Does this stuff need to be inlined and if not would that solution avoid the breakage? Accurately predicting the future is impossible (IHMO, I guess others disagree). Breaking forwards compatibility if necessary will happen. Doing it when there is an alternative that's viable and wouldn't break it is what should be avoided. --=20 Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel | --=-EE0FUETTzSF02cd1t5na Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQBHIg82/G14VSmup/YRAuRXAJ9oJVZgppxZlBpRhguL4E/wtMIkYgCfStZB zgdKzH4kbe56pvt9WtoOCVc= =KKE+ -----END PGP SIGNATURE----- --=-EE0FUETTzSF02cd1t5na--
