Subject: Comparable, String and ==

Maybe I'm doing something very stupid, but consider this.

The following little program:

class Awk < String
  include Comparable
  
  def <=>(other)
    puts "I am called"
    super
  end
end

a = Awk.new('a')
b = Awk.new('a')
if a == b
  puts 'Equal'
end
if a < b
  puts 'Hurrah'
end

produces, quite against my expectation,
Equal
I am called

Which means that Awk#<=> isn't called for ==
Both on 1.6.8 and 1.8.0
This _must_ be my mistake, but I just don't see it.

Suggestions ?
