Is there a ruby equivalent of "using" to help with namespaces?

ruby-talk

module Rfc2425
class DirectoryInfo
class Field
end
end
end

I believe something like this is common:

include Rfc2425::DirectoryInfo

f = Field.new
f2 = Field.new

Example of usage:
require “with”

class Fish
attr_reader :type, :name

def initialize(type, name="percy")
	@type=type
	@name=name
end

def moo(*args)
	return "#{name} (a #{type}) says moo and #{args[0]}\n"
end

end

a=Fish.new(“halibut”)
b=Fish.new(“turbot”, “martin”)
c=Fish.new(“hake”)

with (a) { print moo("[default]"); print b.moo("[other object]") }
with (b) {
print moo(“pre-nest”)
with © { print moo(“nested”) }
print moo(“post-nest”)
}
