I stuck this fix in my conda install of snakemake to get the job grouping feature working ASAP and had to make a few small changes to the new function before it would work:

def merged_wildcards(self):
        merged_wildcards = Wildcards(toclone=list(self.jobs)[0].wildcards)
        for job in list(self.jobs)[1:]:
            for name, value in job.wildcards.items():
                if name not in merged_wildcards.keys():
                    merged_wildcards.append(value)
                    merged_wildcards._add_name(name)
        return merged_wildcards

I'm way out of my depth here in software development terms, but I wrapped references to the frozenset self.jobs in list so that I could subscript them and replaced _set_name with _add_name as the former was missing the required index argument. I hope this helps.

Sorry for the silence. Thanks for the suggestions! Will try to merge this ASAP.
