Like David B. said.  Also, if you left off the assignment, it would be
more like arr.drop! since it's destructive, which the docs don't
imply.  I love shift and unshift for all kinds of things, but I would
go with indices (you could use slice, too).

I haven't played with 1.9 or 1.8.7, but I'm assuming that drop simply
returns arr[n..-1] without affecting the original array.
