Also, I'm fine with
(substring "abc" -1 1)
=> #ERROR
so using ̀condition-case' would not help me distinguish
between the case above and (substring "abc" 0 4), which
is what I want.
I see the benefit of having
(substring "abc" 0 4)
=> "abc"
in terms of simplifying Elisp writing -- and I still fail
to see the harm (but maybe Pascal will tell me where he has
been bitten by this.)
