This 'alpha' is an interesting useful feature I didn't know. Thanks.
(It will go into my .vimrc file.)

Testing it I was a bit astonished, though, that (and different from
numbers) it just works on single letters without a "carry"; with the
string "say38", operating a 66^A on the number part creates "say104"
while at any character it stops increment at "z".

(I recall that I once had a requirement to enumerate some date as
aa, ab, ac, ..., az, ba, bb, ..., bz, ..., zz, and even continuing
zz with aaa, as with a numeric carry.)
