But 'self' is still defined within that block even if it isn't  
'used'.  It is a pretty fundamental concept in Ruby that 'self' is  
always defined.  I realize that in the
functional world a lambda only uses its arguments for input, but in  
the Ruby world
there is always an implicit receiver hanging around.
