The simple answer is, go look at @partial's __call__: https://github.com/markshroyer/pointfree/blob/master/pointfree.py#L468 https://github.com/markshroyer/pointfree/blob/master/pointfr... All that code is executing on every partial call. So, a very brief list of reasons not to use this in production: 1. overhead 2. complexity 3. debugging 4. don't fight the language edited to add: I just want to emphasize that I think it's a really, really neat hack!
