Functions that return a value are chain-able. I suppose this is true in
LUA too.
$int = function($txt){
return parseInt($txt,10);
};
$hats = function($numHats){
return " We have $numHats excellents hats! ";
};
echo $hats( $int("4123,234") );
Perhaps this make functions that return a string slightly better.
