Subject: Ruby block: why doesn't this work?

I'm trying to figure out why my code isn't doing what I think it
should...

Basically, I'm trying to create a Info object, and do various things
to that new object within the block.  For what ever reason though, it
doesn't look like the code inside the block is getting executed at
all.  (I'm trying to do something that looks kind of like
activerecord's create_table method.)

So... with the print statements in the code, I'd expect to see output
from the address() and city() methods, but only the initialize method
prints anything.  (I can even put complete nonsense in the address or
city methods, and nothing happens.)

What am I doing wrong?

Thanks!

class Info
  attr_accessor :name, :address, :city

  def initialize(name)
    @name = name
    print "name: #{name}\n"
  end

  def address(value)
    @address = value
    print "address: #{address}\n"
  end

  def city(value)
    @city = value
    print "city: #{city}\n"
  end
end

def info(name)
  Info.new(name)
end

info :Bob do |i|
  i.address "123 Main St."
  i.city "Boston, MA"
end
