Kevin Wortman scripsit: > It's too bad end-of-file isn't just called "end" in R7RS. Or something like "end of data" or "end of values", yes. > make-circular-generator, list->circular-generator: Splitting hairs, but > "circular" may not be the best word since it usually describes geometric, > not discrete, objects. How about "repeating"? Circular in the same sense as circular lists. I'll point this out. > make-iota-generator: count must be an integer right? No, arbitrary real numbers are allowed. > "a sequence of boolean values": capitalize Boolean since it is derived > from Boole's name. That's not the RnRS convention; cf. "abelian group". > make-for-each-generator: obj may be any kind of "collection" but AFAICT > that term doesn't have a precise meaning here. No, it doesn't. > gmerge, gunion, gintersection: The description talks about order but is > unclear on whether it means increasing or decreasing order. How about > saying "elements in strict increasing order according to a SRFI 114 > comparator". The "strict" qualifier implies there are no duplicates in the > input. Increasing order, yes. I see no reason to forbid duplicates particularly. > I think gmerge is capitalized by mistake. I'll rewrite to avoid that. > As in SRFI 113, there is the issue in set union that input sets may have > elements that are equal according to the comparator but not eqv?. How > about > copying the SRFI 113 language: "Elements in the result set are drawn from > the first set in which they appear." Yes. > SRFI 113 also has set difference and xor, include those in SRFI 121? I suppose that's feasible, yes. > gtuple: I understand why gzip would be a poor name. This operation is > similar to transposing a matrix, would gtranspose be any better? Either works for me. > How about syntax greceive that binds a fixed number of elements to > identifiers, similar to SRFI 8 receive? Excellent idea. -- John Cowan http://www.ccil.org/~cowan cowan@xxxxxxxx Evolutionary psychology is the theory that men are nothing but horn-dogs, and that women only want them for their money. --Susan McCarthy (adapted)
