Subject: Splitting an Array

I have and Array and I need to iterate over it, finding a subset of the 
elements it contains.  I want that subset in a new Array and I want the 
original Array altered so it no longer contains the subset.

The following code does what I want, but it seems kind of "clunky":

a = [ 1, 2, 3 ]
b = [ ]	# so it exists outside the iterator

puts a.delete_if { |e| b << e if e > 1; e > 1; }	# prints 1
puts b	# prints 2 and 3

Is this the best way to go about it?

Thanks.
