There can be problem with string vs numeric comparison:

use v5.10; ( $RB1, $RB2, $WR1, $WR2, $TE1 ) = (1,2, 3, "05", 5); if( keys %{ { map{ $_,$_ } $RB1, $RB2, $WR1, $WR2, $TE1 } } == 5 ) { say 'all different'; } else { say 'some same' };; prints "all different"

    Indeed.

    For strictly numeric comparison add 0+:

    if( keys %{ { map{ 0+$_,$_ } $RB1, $RB2, $WR1, $WR2, $TE1 } } == 5 ) { + say 'all different' } else { say 'some same' };;

      Yes, that would work.
