The singledispatch package does not exist in nixpkgs and needs to be packaged up.

The sexpdata package currently has no dedicated maintainer, so maintenance falls back to the python package set maintainers, but we don’t have time to deal with every package.

Feel free to step up to the occassion.

First of all, I’m not really sure where this is coming from? I didn’t put singledispatch into my configuration file, so where did it come from?:wink:

It is a new dependency, that sexpdata requires from version 0.0.4.

But with 1.0.0 it was constrained to python<3.4, so an update fixes it.

I don’t have sexpdata, either, so this is something that these require somehow?

sexpdata is a dependency of epc.
