Do you have a real example where this would be genuinely useful? 1) If you are only creating a wrapper around simple C source, then you need to know very well whether you are dealing with unicode or bytes anyway (and encode explicitly to the right representation). 2) If you are doing anything more advanced, odds are you are using the standard library anyway, and then your code will more than likely break between Python 2 and 3 anyway (from what I hear). My very subjective and unfounded feelings: Creating some super-language which supports both 2 and 3 completely transparently is likely going to either have too few features to be useful, or be such an effort that it's not worth it. Having Cython output Python 3 compileable C code (from current Cython/Python 2) is however a great way of enabling people to write Python 3-specific Cython code before we get to the stage where there is Python 3 syntax support in Cython itself. (BTW, can we find some standard terminology for talking about this? Something like "Cython": pyx -> c stage; then it is a c-file and not Cython, and then "C compilation": c -> executable stage.) -- Dag Sverre _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
