Perl 5 still does exactly this - there is no !~ opcode - the compiler just generates the optree for ! of =~, and it is indistinguishable from it: $ perl -MO=Deparse -e 'print if $^X !~ /perl/' print $_ if not $^X =~ /perl/; -e syntax OK $ perl -MO=Deparse -e 'print if not $^X =~ /perl/' print $_ if not $^X =~ /perl/; -e syntax OK Nicholas Clark
