I'd like to see:

    (k)  Hash#[],  Array#[]

as in:

    myHash = {'one' => 1, 'two' => 2, 'three' => 3}

    myHash['one','two','three']    ->  [1,2,3]

and

    myArray = [1,2,3,4,5]
    myArray[4,2,3]                     ->  [5,3,4]

I realize that this latter conflicts with:

    Array#[<beginning index>, <number of elements>]

but that functionality is duplicated by:

    Array#[<beginning index>..<beginning index + number of elements - 1>]

anyway.
