Subject: Re: Fixnum <=>

I may be missing something obvious . Why  is the '<=>' operator not
called  when there is no block supplied to sort ?.The Pickaxe book
says ( apropos  Array.sort ):
  " Comparisons for the sort will be done using the <=> operoator OR
     using an optional  code block"
How is the comparison done in the  second case ?

class   Fixnum 
  alias oldcmp <=> 
  def <=>(other)
    puts " <=> called with #{self} and #{other} "
    oldcmp(other)
  end
end

p  [9,1,7,3,5].sort { |a, b| a <=> b}
p  [99,11,77,33,55].sort
