Subject: why do the methods from my mixed-in module disappear?

Have a look at this piece of code:

module Foo

  require 'soap/driver'

  class Search
    include SOAP
    attr_reader :key
    def initialize(k)
      Endpoint = 'http://www.foo.com/foobar/'
      Ns = 'urn:fooService'
      @key = k
      a = SOAP::Driver.new(nil, nil, Ns, Endpoint)
      puts a.methods
    end
  end
end

In the above Foo module, I'm mixing SOAP into my Search class. The
call to puts is there to verify that all the expected methods
associated with the SOAP object are available to me. The SOAP object
is then returned to the caller.

The calling code looks like this:

require 'foo'
key = 'abc123'
f = Foo::Search.new(key)
puts f.methods

Here, however, the call to puts does _not_ display the same list of
methods as the call to puts in the constructor.

My question is: why are the SOAP object's methods not passed back when
returning from the constructor method? I would expect the mix-in of
SOAP to make these methods available in the caller.

Clearly, I'm misunderstanding something.
