RCR 156: Enumerable#zip(an_enumerable)

Submitted by flgr (Wed Oct 01 19:10:40 UTC 2003)


This is a legacy RCR from Ruby Garden, submitted by flgr. Matz has declared these RCRs obsolete, and asked that their authors resubmit them in the new format.

I'm not sure whether this is a bug or just a missing feature, but #zip seems to be lacking some symmetry:

("a".."b").zip([1, 2]) # => [["a", 1], ["b", 2]]
[1, 2].zip("a".."b") # TypeError: cannot convert Range into Array

IMHO both should produce the same result which I'd assume to be no exception.

huh, Range#to_ary seems to be not-defined, while to_a is... any particular reason why that implicit casting is missing?
