> For example, though Java forces one to put all stand-alone functions as static methods on a class (like Metrics) in Python one would just have standard module-level functions. 
> Also, the MetricsFilter builder pattern is very Java-esque (and verbose). In Python, one would simply let result.metrics() take keyword arguments. 
> We should seriously consider aggregating rather than returning lists of results, at least by default. E.g. in https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/wordcount.py it assumes that there's no other metric with the given name in any subtransform (otherwise it may deterministically grab the "wrong" one.)
