for (var i=0; i<5; ++i) {
  var someString = strings[i];

'return' meaning different things semantically

	// This is just a toy example, but it demonstrates the semantic
	// overloading of the 'return' keyword when blocks are in play.
	// Note that I'm not saying this is confusing, per se - I'm just
	// saying that it adds cognitive load as I look at the method and
	// try to figure out which 'return' statements actually represent
	// an early return.
