[Python] Python - showing 'once' warnings again (resetting all warning registries)

is there a way to reset the __warningregistry__ of all loaded functions at once?

I would like to force all warnings that are filtered with the 'once' filter to show again. I have found no way of doing this aside from calling <func>.__globals__['__warningregistry__'].clear() on every function that I have loaded (including those that are part of an imported module.)

So, what I want is something like a warnings.clear() function to do the following:

>>> import warnings
>>> warnings.warn('blah')
WARNING:root:blah ->UserWarning at ...
>>> warnings.warn('blah')
>>> warnings.clear()
>>> warnings.warn('blah')
WARNING:root:blah ->UserWarning at ...


And I want this warnings.clear() function to also clear all warning registries, not just the current name-space.

Is this already existent? Perhaps I'm missing something obvious, or using the module incorrectly?
