Hi Victor,

On CPython, --duplicate makes sense (no?). So for example, the following command should use duplicate on CPython but not on PyPy:
python2 -m perf timeit '[1,2]*1000' --duplicate=1000 --compare-to=pypy
This example means "compare CPython where the data cache gets extra pressure from reading a strangely large code object, and PyPy where the multiplication might be entirely removed for all I know".
Is that really the kind of examples you want to put forward?
A bientôt,
Armin.
