Hmmm.... no-one's taken the ball...

I have two or three times now wished that Array#shift(n) was implemented.

   (quickly checks that it's not...)

As in:

  x = [1,2,3,4,5]
  x.shift                 # => 1
  x.shift(2)              # => [2, 3]

I can (now) sort of see why that might be a bit irksome - returning different
types - but in practice:

  foo, bar = ARGV.shift(2)
  baz      = ARGV.shift

That would work under the specification-by-example above.  I know I can use
#slice!, but #shift just seems so right.
