    py.bench description follows:
    
    """
    py.bench, similarly to py.test, discovers bench_* functions and Bench* classes
    and then runs each discovered benchmark via golang.testing.benchmark. Similarly
    to `go test -bench`, benchmarking results are printed in Go benchmark format.
    
    For example, running py.bench on the following code::
    
        def bench_add(b):
            x, y = 1, 2
            for i in xrange(b.N):
                x + y
    
    gives something like::
    
        $ py.bench --count=3 x.py
        ...
        pymod: bench_add.py
        Benchmarkadd    50000000        0.020 µs/op
        Benchmarkadd    50000000        0.020 µs/op
        Benchmarkadd    50000000        0.020 µs/op
    """
    
    The implementation is based on t/py.bench from Wendelin.core - see
