Subject: Module intercepts containing class's initialize method?

I'm wondering if something like this is possible:

  module Intercept
    def intercept_initialize
      puts "performing Intercept#intercept_initialize"
      # somehow call containing class's 'initialize' method here
    end
  end

  class Foo
    def initialize
      puts "performing Foo#initialize"
    end
  end

  class Bar
    include Intercept
    def initialize
      puts "performing Bar#initialize"
    end
  end

  puts "instatiating Foo"
  Foo.new
  puts "instatiating Bar"
  Bar.new
  puts "done"

Desired results:

  instantiating Foo
  performing Foo#initialize
  instantiating Bar
  performing Intercept#intercept_initialize
  performing Bar#initialize
  done
    
In other words, simply by including the "Intercept" module in a class,
I'd like to intercept that class's call to "initialize" and have the
Intercept module's code get invoked first, and _then_ the containing
class's "initialize" method should be called as it normally would.

Is this possible?  If so, how?

Thanks in advance.
