[pythran] question on slice.hpp

In pythran/pythonic/types/slice.hpp
long size() const
{
assert( not upper.is_none and not lower.is_none and not
step.is_none );
return std::max(0L, long(ceil(double(upper -
lower)/double(step))));
}
Maybe this should be:
(using python code here:)
def roundup_divide (a, b):
return (a + b - 1) // b
return std::max(0L, roundup_divide (upper-lower, step));
But on the other hand, did you really mean to roundup? Should the size of
a slice be rounded down?
