The warnings module makes use of a per-module global ``__warningregister__`` which is briefly mentioned in the docs but not documented. https://docs.python.org/3/library/warnings.html#warnings.warn_explicit Given that it is part of the warn_explicit API, we should accept that the registry file is now part of the public API not just an implementation detail, and so we should explicitly document its existence and state the expected format. |

I don't think that it is necessary to state its format. It is an opaque dictionary, and its format is an implementation detail. |

And this case looks like playing with implementation details.
The official way to make the specified warning emitted more than once is to use warnings.filterwarnings():
>>> import warnings
>>> warnings.filterwarnings('always', "NOBODY expects the Spanish Inquisition!", UserWarning)
>>> warnings.warn("NOBODY expects the Spanish Inquisition!")
<stdin>:1: UserWarning: NOBODY expects the Spanish Inquisition!
>>> warnings.warn("NOBODY expects the Spanish Inquisition!")
<stdin>:1: UserWarning: NOBODY expects the Spanish Inquisition!
