in thread grep flip flop (range operator)

Edit: Upon further reading, it looks like the range operator isn't parsed in scalar context, as the following does print something: perl -le " print for grep scalar 1 .. /Q/, @ARGV " a b c Q r s

I use    perl -MO=Deparse,-p   what you have is  (scalar(1) .. /Q/)

you need  scalar( 1 .. /Q/ ) to get nothing :)
