_ is unsafe to use

[nils-werner]

_ already has several uses in Python:

• Most REPL implementations assign the last output to it
• It is commonly used in localization
• Some Programmers use it to indicate a return value they don't need

All of this can, as I imagine, lead to very unexpected behaviour.

You can do from pampy import match, ANY. ANY is identical to _. Maybe it's not clear enough from the README.

You can also do from pampy import _ as WHATEVER.

Thank you for the note.
