Only just noticed this line of your comment:

I think it doesn't, since I need most operators already. :/

Not sure what you mean by it. Did you assume that using Sub::Infix takes over existing operators, so you can no longer use (for example) the | or / operators normally? Because that's not what it does. You can continue to use the existing Perl operators normally, with no slow down, but Sub::Infix will allow you to define additional operators like:

use Sub::Infix;
BEGIN {
  *between = infix {
    my ($number, $range) = @_:
    $number >= $range->[0] and $number <= $range->[1];
  };
}

if ($value <<between>> [1,10]) {
  ...;
}

The only limitation is that your infix operator can't be spelled just between. It needs to be |between|, /between/, or <<between>> (and depending on which you choose, you'll get different precedence).
