...Is the result of extracting past the end of a subsequence
considered undefined?
Stever
Yes. Although it isn't explicitly stated when :END is discussed on
page 246, the discussion doesn't make any sense otherwise. One could
hypothesize a magical exception in the case where END is greater than
the length, but there is nothing in the manual to support such a
conclusion. There are many illegal things which are not explicitly
stated to be illegal in the manual.
