It's working for me...
{{{
%cython
print any([0,0,1,0]), all([0,0,1,0])
///
(True, False)
}}}

This was actually discussed recently, and yes, we'd like to support
this kind of thing. It shouldn't be too hard to do either. However,
it's hard to see how one would get faster than the builtin
implementations of all and any, short of getting rid of the Python call.
For (some) builtlins, it might be interesting to extract and call the
C function pointer directly. This could give a good speedup for
builtins...
