Hi all, I curate the multipledispatch library on PyPI. I believe that it is a natural continuation of singledispatch outlined in PEP 443 and included in functools 3.4. For those unaware, dispatching correctly and unambiguously on multiple inputs is a somewhat more complex problem than on a single input. I believe the approach taken in multipledispatch is fairly robust. I wrote a blogpost about MD a while ago: http://matthewrocklin.com/blog/work/2014/02/25/Multiple-Dispatch/ The docs pages live here: http://multiple-dispatch.readthedocs.org/en/latest/ And the github page lives here: https://github.com/mrocklin/multipledispatch Recommendations for improvement welcome. Thoughts on whether or not this is appropriate to include in the standard library also welcome. Best, -Matthew Rocklin
