Add existing classes into a module

Question

I have some existing ruby classes in a app/classes folder:

class A
   ...
end

class B
   ...
end

I\'d like to group those classes in a mod

Answer 1

module Foo
  A = ::A
  B = ::B
end

Foo::A.new.bar

Note that the :: prefix on a constant starts searchign the global namespace first. Like a leading / on a pathname. This allows you differentiate the global class A from the modularized constant Foo::A.
