Having established this range for each correspondingly indexed letter, the
range for multi-character strings is defined by a left-significant counting
sequence. For example:
"Ab" .. "Be"
defines the ranges:
<A B> and <b c d e>
This results in a counting sequence (with the most significant character on
the left) as follows:
<Ab Ac Ad Ae Bb Bc Bd Be>
glob can do that:
perl5.8.5 -wle 'print for <{A,B}{c,d,e}>'
Ac
Ad
Ae
Bc
Bd
Be
Currently, Rakudo produces this:
"Ab", "Ac", "Ad", "Ae", "Af", "Ag", "Ah", "Ai", "Aj", "Ak", "Al", "Am",
"An", "Ao", "Ap", "Aq", "Ar", "As", "At", "Au", "Av", "Aw", "Ax", "Ay",
"Az", "Ba", "Bb", "Bc", "Bd", "Be"
which I don't think is terribly useful.
Good enough for me. For your variant, just override the .. for 'smarter'
behavior?
