[issue19229] operator.py: move the Python implementation in the else block of try/except ImportError

[Stefan Krah]

Stefan Krah added the comment:

Using the microbenchmark I get (standard version):

./python -m timeit "import sys; modname='operator'" "__import__(modname); del sys.modules[modname]"
1000 loops, best of 3: 460 usec per loop


Victor's version:

./python -m timeit "import sys; modname='operator'" "__import__(modname); del sys.modules[modname]"
1000 loops, best of 3: 355 usec per loop


Importing _operator directly:

./python -m timeit "import sys; modname='_operator'" "__import__(modname); del sys.modules[modname]"
10000 loops, best of 3: 35.7 usec per loop


Extrapolating from what I did with decimal, I guess a _pyoperator
version could get down to something like 70 usec.
