The closest Ruby equivalent to Perl's splice(\@a,$i,$n,$v) function is
Array#[i,n]=v; the big difference is the return value. It can be
implemented like this:

	class Array
	  def splice(i,n,v)
	    r = self[i,n]
	    self[i,n]=v
	    r
	  end
	end

Or like this:

	class Array
	  def splice(i,n,v)
	    r = slice!(i,n)
	    self[i,0]=v
	    r
	  end
	end
