class Module
  # Very similar to Facets' +Module#nesting+, but, whereas +nesting+ will break <tt>A::B</tt> into an array of _constants_ represting nesting
  # (<tt>[A, A::B]</tt>), this method will split it into an array of _symbols_: <tt>[:A, :B]</tt>.
  #
  # Note that the second element in this array, <tt>:B</tt>, is _not_ fully qualified, so you could not do a <tt>const_get</tt>
  # on that symbol.

  # Like Module#split, only this operates on a string/symbol. Useful for when you don't want to or can't actually instantiate
  # the module represented by the symbol.
