Ah, that’s right, I meant singledispatch. Sorry for the confusion! :) -- Best regards, Łukasz Langa WWW: http://lukasz.langa.pl/ Twitter: @llanga IRC: ambv on #python-dev On Aug 15, 2014, at 11:33 AM, Matthew Rocklin <mrocklin@gmail.com> wrote:
I assume that Lukasz is referrring to singledispatch? multipledispatch doesn't yet have that level of adoption as far as I'm aware.

My implementation was influenced somewhat by Julia's solution which seems fairly sober. Multiple dispatch has demonstrated value in that community.
I used the multipledispatch library in a few of my projects. I can provide examples of where it's been helpful if desired.

In one of my projects, I have a todo item to convert a homegrown {type:func} dictionary based dispatch to singledispatch. It has been open for 5 months already. I wouldn't be surprised if others had something similar: a good-enough (and probably buggy) solution that is not bad enough to justify adding extra dependency in 2.x or replacing with a 3.x only solution.
Multiple dispatch is much harder to get right or even "good enough," so I don't think singledispatch popularity or lack thereof is a good predictor for multipledispatch.
