Subject: Kernel.y and yes,yes,yes not least surprise

Sometimes using emacs makes me think of Molly Bloom (never a good idea 
at work) and then I just answer yes even before the question is asked. 
Today this resulted in a confusing bug.

h.each{ |k,v|y

did not produce an error but rather caused my script to output a bunch 
of "---"'s.

I propose that Kernel.y should demand at least one argument

def y(o,*x)
	puts( if x.empty?
			YAML::dump( o )
		  else
			YAML::dump_stream( o, *x )
		  end
		)
end

_why what do you think?

maybe the convention that all one letter methods demand arguments might 
even be considered for inclusion in the ruby style guide.
