+-----------------
 
 The Python module loader system is hard-coded to prevent the discovery
 of heterogenous source code packages.  From Python 2.6 through the
-current (as of this writing) Python 3.5, the import mechanism allowed
-for the creation of file finders and importers that would transform
-Python's import syntax into a *path,* assert whether or not that path
-could be made to correspond to a *syntax object*, and then attempt to
-*load* that syntax object as a Python module.  Python *packages*,
-however, are assumed to be uniformly made up of Python syntax objects,
-be they **.py** source files, **.pyc/.pyo** bytecode, or **.so/.dll**
-files with an exposed Python-to-C API.  In Python 2 these suffixes are
-hard-coded into the source in the **imp** builtin module; in Python 3
-these suffixes are constants defined in a private section of
-**importlib**; in either case, they are unavailable for modification.
-This lack of access to the extensions list prevents the *discovery* of
-heterogenous source code packages.
