Subject: [ruby-talk:14570] why doesn't do/end work for sort block?

Hello --

Just wondering why:

  ary = [1,2,3,4,5]

  p ary.sort {|a,b| b <=> a}
  # => [5, 4, 3, 2, 1]

  # but

  p ary.sort do |a,b| b <=> a end
  # => [1, 2, 3, 4, 5]

  # and even
  p ary.sort do |a,b| puts "Hi!" ; b <=> a end
  # => [1, 2, 3, 4, 5]


The do/end blocks seem to be discarded.  Same for Enumerable#max and
#min.
