Subject: Re: each with separator

		  [1,2,3].separate_by { puts "-" }.each {|obj|
		    puts obj
		  }
		
		desired output:
		
		  1
		  -
		  2
		  -
		  3
		

puts [1,2,3].collect{ |o| o.to_s }.join( "\n-\n" )
 
I feel certain that I'm missing the real point of separate_by, but there you have it, FWIW.
