in reply to Re^6: open undefin thread open undef
Yes, it's a known bug.
It bit me today when I was consolidating several stand-alone scripts into one script when I forgot to change one occurence of $ARGV[0] and did not get the error I expected.
Would reporting it again speed up anything?
It might have been more precise to say "known limitation". I don't know if it's considered a bug. After all, undef was passed.
