Re: [Scheme-reports] final draft of the R7RS small language

[Shiro Kawai <shiro.kawai@x>]

Thanks to all who worked on this.  Congratulations.

The latter half of this prose in eq? entry is the addition in this draft (p.31):

    The eq? procedure is similar to eqv? except that in some 

    cases it is capable of discerning distinctions finer than those

    detectable by eqv?. It must always return #f when eq? also 

    would, but may return #f in some cases where eq? would

    return #t.

Does the subject "it" in the second sentense means 'eqv?'?  I'm a bit

confused, for taking this "it" as `eq?' and replacing the two `eq?' in

the sentence for `eqv?' seems to make more sense, making the second

sentence augmenting the first sentence.

Does the new sentence specifically tell there's a case that (eq? a b) => #t but (eqv? a b) => #f?

The 10th and final draft is available at:

This includes the changes from the 9th draft listed at

  http://trac.sacrideo.us/wg/wiki/NinthDraftEditorialCorrections

The only significant change was the reversal to the R5RS

semantics for eq? and eqv?, as discussed earlier on this

list.  Any further changes will be collected in a separate

errata document.

I'd like to thank the WG members for all their hard work

over the past three years, in particular John Cowan and

Arthur Gleckler.  I'd also like to thank the Steering Committee

for their guidance, and the editors of the R6RS, R5RS and

earlier reports, and SRFIs which form the basis of the report.

Mostly I'd like to thank the community for their constant

feedback.  We did our best to make everyone happy, and

no doubt fell short in some areas, but we're proud of the

result.

The work is not over, of course.  WG2 is actively seeking

volunteers to help with standard libraries, which are using

the SRFI process.  If you wanted more say in the small

language, now is your chance to join in!
