But is it (just) that? ^5 0 .. 4 ^$n 0 .. $n-1 [EMAIL PROTECTED] 0 .. @a.elems-1 (usage deserves a warning) [EMAIL PROTECTED] zip: @a.keys? @a.indices? ?? 0 .. @a.last-1 (no sc ncsry, prbly no need @all) ?? 1 .. $n (no sc ncsry, or use base-0) ?? 0 .. $n+1 (no sc ncsry) > Indexes and numbers (counts) just aren't the same thing, and I think > source code should communicate meaning using the right words. Indices can be sets of sparse ranges. A sparse range is a set of non-sparse ranges.
