Hallo, Here're two new list-abs, list-range and list-zip.
list-range spits out sequences from n1 to (n2 - 1), optionally separated by a positive or negative "step" interval m. It's based on Python's range() function[1]. You can either use it as a shortcut by specifying creation arguments and [bang(ing it, or send in one, two or three arguments to get a new sequence (n1 (for 0...n1-1), n1 n2, or n1 n2 m).
list-zip interleaves lists of equal length to produce a new list. It defaults to two lists, but uses dynamic patching to modify its inlets to accept an arbitrary number of lists. So, for example, [1 2 3 4( and [A B C D( would become [1 A 2 B 3 C 4 D(. list-zip is based on Python's zip() function[also 1].
Regrettably[2] list-zip requires [initbang] for its dynamic inlet creation, but list-range is a purely vanilla affair, requiring only the existing list-abs from Frank's library.
Inside the help for list-zip, you'll find a recreation of list-enumerate using 4 objects.
Cheers Luke
