. . . If DLW is right that end positions
are more available than counts anyway, then the subtraction JONL fears
will turn up anyway:
(STRING-SUBSEQ FOO START (- END START))
(SUBSTRING FOO START END) ;compilation requires a subtraction
. . .
This thought has occurred to us, that despite one's best efforts, he's going
to find that he has a Left-foot shoe when he wants a Right. However,
I took DLW's remarks to be personal stylistic preference, since it's so
hard to get data on just which case is more frequent/convenient. At least
for some of the overlapping functions, one will have, in NIL, a choice.
By the bye, when did the late "Great" become a "Gronked" Quux?
