in thread boolean IN(); function in perl like

Or List::MoreUtil's even more correct 'any' function.
if ( any { $_ eq $foo } @list ) { }
If you are wondering why first isn't enough, imagine...
if ( first { ! defined $_ } @list ) { # Does not get called if it matches } if ( any { ! defined $_ } @list ) { # Does get called it if matches }
Of course, this assumes you only need to check once and once only. If you want to check many times, build the hash index and do it that way.
