[issue28939] Groupby Is Roughly Equivalent To ...

[Greg Solomon]

Greg Solomon added the comment:

Oh, I get it. There needs to be a next(self.it) loop in __next__ as well as in _grouper in case the user doesn't call _grouper.

My test was 
for ( k , g ) in groupby( L ):
    print ( k , len( list( g ) ) )
so I was executing _grouper on every row.

Thanks !!!
