I don't think so.  It makes constants globally scoped (well, mostly).
Those rules provide you the "illusion" of statically scoped constants.

  module C
    CC = 1
  end

  module A
    include C
    puts CC     # accessible because A includes C
    AA = 2
    module B
      puts AA   # accessible because B in the scope AA is defined
      puts CC   # no CC in ancestors, nor outer scope
    end
  end

For most of the cases, static scope is better than dynamic scope.

For most of the cases, dynamic typing is better than static typing.
