http://docs.python.org/reference/datamodel.html and Python's source
code (Objects/moduleobject.c):

It is an object of type/class "module". Type module has exactly one

__dict__ (read-only): the module's namespace as a dictionary

  __dict__ is the dictionary of attributes of the object. That is, if
  there is no member BAR in object FOO, then FOO.BAR is

__dict__ is prepopulated by the module loading system with:

_name__ is the module’s name

__doc__ is the module’s documentation string, or None if unavailable

__file__ is the pathname of the file from which the module was loaded,
  if it was loaded from a file. The __file__ attribute is not present
  for C modules that are statically linked into the interpreter; for
  extension modules loaded dynamically from a shared library, it is the
  pathname of the shared library file.

But they are read/write and can be freely changed by Python code.

The code you quoted looks right. I would then continue with:

 if inspect.isroutine(implHelper):

to test whether implHelper is a function (something that takes
arguments and returns a result) as I guess it is expected to be. The
inspect module having been loaded, obviously.
