What do you mean?

You know, modules are objects, constants are stored in modules. Given  
those rules you can put a module almost anywhere. AFAICT what you  
cannot change via API is its name, which is set in stone the first  
time a module is assigned to a constant. That happens in regular  
module definitions, or explicitly like this:

     $ irb
     irb(main):001:0> m = Module.new
     => #<Module:0x20eb6c>
     irb(main):002:0> m.name
     => ""
     irb(main):003:0> M = m
     => M
     irb(main):004:0> m.name
     => "M"
     irb(main):005:0> N = M
     => M
     irb(main):006:0> N.name
     => "M"
