Subject: Re: [RFC] Match expression
From: gmblar@gmail.com (Andreas Treichel)

Hi,

Something like:

function match($x) {
     switch(true) {
         case $x === 1:
             return 'Tiny';
         case is_numeric($x) && $x <= 10:
             return 'Small';
         case is_numeric($x) && $x <= 20:
             return 'Medium';
         case is_numeric($x) && $x <= 30:
             return 'Large';
         case is_numeric($x) && ($x >= 31 || $x <= 100):
             return 'Enormous';
         case $x instanceof Foo:
         case $x instanceof Bar:
             return 'What?';
         default:
             return 'Unknown';
     }
}

the problem is you need is_numeric because no type safe version of <= 
and >= exists.
