Re: Proposal to evaporate OBJC_INT_SELECTORS

[Ovidiu Predescu <ovidiu at cup dot hp dot com>]

Sounds fine with me, GNU Objective-C never used them anyway.

Just as a curiosity, how do selectors look like these days in Apple's
Objective-C runtime? They used to be only a reference into a
hash-table of selector names, with no types associated. This contrasts
with the GNU Objective-C runtime, where a selector is a pointer to
both a selector id and the types of its arguments and return value.

Thanks,
