Hi Pythraners,
Numba and parakeet are using a @jit decorator on functions to trigger
jit compilation of python function to modules. I first thought it would
be a good idea to do the same in Pythran.
After seeing

at scipy and following the cython tutorial, it appears to me that:
* users are happy with the way cython waork, and pythran is very similar
to it
* jit typing will give a bad user experience as compilation is really
slow
However, distutils integration, as done in cython, seems useful
any thought?
@Joker: sorry, I hope you did not go to far in the dev...
IMO distutils integration in cython is really bad.
Even if you just want to do a test, you have to write a specific
distutils files and after some test, you have a lot of files everywhere
and you don't know what is matching with which other file. Of course you
can say that it is the user who should sort his files but why should we
change the way pythran works to something worse?
May be I didn't understand why it is good...
About JIT, we can provide both interface. The one we have now and a jit
too, isn't it?
I think that something more important than decorator @jit is to compile
only decorated functions in a file. For example, if we have a class and
many function in a file. It can be good to compile only annotated
function without crashing because of (not supported) class.
In this case, annotated function can be jit if they are not already
compiled? (jit is only a "plus" in this case, not the main feature)
