What if it's "set once"? It's treated as essentially frozen after it's
set for the first time. Something like:

  def Encoding.default_internal=(encoding)
    raise "Internal Encoding Already set" if @default_internal_set
    @default_internal_set = true
    @default_internal = encoding
  end

It would be treated as read-only if set by a command-line parameter or
after the first time it's set to an explicit value.

This would discourage people from setting it in libraries (it would
break automatically).
