I thought about what was missing and it seems to me that it could be

(and will be more and more) compared to Julia, I think it becomes
necessary to have a good tool to write efficient numerical codes in pure
Python style.
Hi Pierre,
I assume that you've had a detailed look at Cython, hand't you? All three
points that you've listed are solved there in one way or another.
Of course, it comes with its own set of tradeoffs / disadvantages, but in
my scientific life I can't say I was really constrained by them, because
Cython blends with Python so naturally (per module and per function), so I
was actually always starting with pure Python and then going down up to
the level of SIMD assembly for 1% of the code where it actually mattered
(99% time was spent)... plus the whole MPI story for scaling.
I'm afraid the situation is simply so good that there is too little
motivation to solve this in Python itself :-/ and solving it in Python has
its own problems. I guess first one really needs to find cases, when
solving it in Python is rationally mandated to gather enough momentum.
