This is a shame.  I understand that it is necessary for compatibility
with S, but I really preferred the more rigorous approach of R. I found
quite a few bugs running programs under R which slipped by unnoticed in S.

Would it be possible to have an option which switches off stretchy vectors
for people who want to write cleaner and more efficient code? And does
anyone else want this?
