Facets has a Kernel method #constant:

  def constant(const)
    const = const.to_s.dup
    base = const.sub!(/^::/, '') ? Object : ( self.kind_of?(Module) ?
self : self.class )
    const.split(/::/).inject(base){ |mod, name| mod.const_get(name) }
  end

So something like:

  class Module
    def enclosing_module
      constant(name.split('::')[0...-1].join('::')
    end
  end

I am all ears for improvements to the implementation.
