There is one case where Rakudo's current output makes more sense then
your proposal, and that's when the sequence is analogous to a range of
numbers in another base, and you don't want to start at the equivalent
of '0000' or end up at the equivalent of '9999'. But that's a less
usual case and there's a workaround. Using your method & example, "Ab"
.. "Az", "Ba" .. "Be" would reproduce what Rakudo does now.

In general, I like it. Though it does mean that the sequence generated
incrementing "Ab" repeatedly will diverge from "Ab" .. "Be" after 4
