Getting back with a status update on this, the thread is still rolling
and benchmarks getting taken on the Cython list.
I think it will take some more time. This CEP will be incredibly
important for Cython, e.g. if NumPy starts supporting it then
from numpy import sin
cdef double f(double x):
return sin(x*x)
won't be that much slower than early-binding directly with sin.
It could take another couple of weeks. So for Numba I think just
starting with whatever is fastest is the way to go now; and then
hopefully one can have the CEP done and things ported over before a
Numba or SciPy release gets into the wild without conforming to it.
