Yeah its actually a method.. Array#<<

it seems to be prefered over Array#push, although they both return the 
array itself so you can string along a load of appending values 
together..

>> foo = [1,2]
=> [1, 2]
>> foo << 3 << 4
=> [1, 2, 3, 4]
>> foo.push(5,6)
=> [1, 2, 3, 4, 5, 6]
>> foo.push(7).push(8)
=> [1, 2, 3, 4, 5, 6, 7, 8]
