Subject: Re: Array.last Weirdness

Array#last= doesn't exist in 1.6 , I don't think it has been added
since.
class Array
	def last= (obj)
		self[length-1] = obj
	end
end
Will give you the functionality you want (but I think you would need to
do array.last += ' world').

Just as an aside, this is a method which could save a lot of typing in
many situations when you are building up an array, it saves you having
to type arr[arr.length-1]= all over the place.  Shouldn't it be added?
