L.s.

REPL code shows

|('az'..'bb')
(az ay ax aw av au at as ar aq ap ao an am al ak aj ai ah ag af ae ad ac
ab bz by bx bw bv bu bt bs br bq bp bo bn bm bl bk bj bi bh bg bf be bd
bc bb)

while I would expect

(az ba bb)

And this

|('x'..'ab')
()

I expected
(x y z aa ab)

Same problem with mixed letters and digits

|('a8'..'b2')
(a8 a7 a6 a5 a4 a3 a2 b8 b7 b6 b5 b4 b3 b2)

I would expect
(a8 a9 b0 b1 b2)

These are alright

|('wt'..'ww')
(wt wu wv ww)

|('b1'..'b5')
(b1 b2 b3 b4 b5)

This is Rakudo version 2016.02-136-g412d9a4 built on MoarVM version
2016.02-25-gada3752
implementing Perl 6.c.

This appears to be a feature, not a bug, as per today's conversation​: http://irclog.perlgeek.de/perl6-dev/2016-07-10#i_12816284

It takes each letter and makes it a range to the corresponding letter on the end point.

To accomplish what you meant, use generate a sequence with .succ method​:

("az", *.succ ... "bb"

As per previous comments, I'm closing this as not a bug. Thanks.
