Two correct ways to use for/in in JavaScript:

for (var i in a) {
  if (!a.hasOwnProperty(i)) continue; 
  
  // loop body
}

for (var i in a) {

SmartInit: Smarter var-args constructors in Ruby

I was working on a small Ruby program today and I repeatedy needed to write classes that can accept a variable number of arguments in their constructors.
