Hi there,

Following this post


I realized that pythran does not support the `or' and `and' operators
the way python does. Not a big deal as we can use intrisic to simulate
their behavior and use something like 

        a or b -> (a?a:b)


An optimization could be to detect that

        (a or b)

is only used for a test, and thus we could generate

        a || b

instead of the more expensive python test. Looks a lot like the on-going
work around range/xrange !
