If you compare PHPs syntax to various others, it is indeed clumsy. Python: map(lambda v: v * 2, [1, 2, 3]) Ruby: [1, 2, 3].map{|x| x * 2} Scala: List(1, 2, 3).map((x: Int) => x * 2) PHP: array_map(function ($x) {return $x * 2;}, [1, 2, 3]); So even a statically typed language like Scala is shorter and better to read. A good improvement would be implicit return and getting rid of the function keyword. array_map(($x): $x * 2;, [1, 2, 3]); But this RFC should come with a patch, otherwise we are discussing things that aren’t necessarily easy to implement. cu, Lars
