Module defining global singleton classes.

|
||||
This module raises a RuntimeError if an attempt to reload it is made. In that
|
||||
way the identities of the classes defined here are fixed and will remain so
|
||||
even if numpy itself is reloaded. In particular, a function like the following
|
||||
will still work correctly after numpy is reloaded::
|
||||
|
||||
def foo(arg=np._NoValue):
|
||||
if arg is np._NoValue:
|
||||
...
|
||||
|
||||
That was not the case when the singleton classes were defined in the numpy
|
||||
``__init__.py`` file. See gh-7844 for a discussion of the reload problem that
|
||||
motivated this module.
