New issue 1782: Test case where pypy is more than 4x slower than CPython
https://bitbucket.org/pypy/pypy/issue/1782/test-case-where-pypy-is-more-than-4x

estama:

I've found a small example where PyPy is slower (more than 4x) than CPython. The \
example calculates all the possible groupings of a list of values. I've attached the \
example's code.

Timings:

time python allgroups.py

time pypy allgroups.py
