Associative array literals:

	string[string] s = ["hello": "world", "foo": "bar"];

Note that an "array" in PHP is always a double-linked list indexed by a 
hash-table. Writing `array(1, 2, 3)` is the same as writing `array(0 => 
1, 1 => 2, 2 => 3)`: what gets constructed is identical. That's quite 
nice as a generic container.
