You can accomplish it by remove_const method

  module Math
    remove_const :PI
    PI = 2
  end

But it requires knowledge about the constants to overwrite.  For
example, to reload the program without error, you have to remove all
constants defined in the program before loading it.

I'm not sure what is the best way.
