Fell free to do so, but don't forget that the choice of a language always 
depends on the specific requirements at hand. Cython has proven its 
applicability in a couple of large projects, for example. And it has a lot 
more third party libraries available than both PyPy and Shedskin together: 
all Python libraries, pure Python and CPython binary extensions, as well as 
tons of code written in Cython, C, C++, Fortran, and then some. And you 
don't have to give up one bit of CPython compatibility to use all of that. 
That alone counts as a pretty huge advantage to some people.
