* Enums can now be declared as cpdef to export their values to
the module's Python namespace. Cpdef enums in pxd files export
their values to their own module, iff it exists.
* Calls to ``slice()`` are translated to a straight C-API call. * Calls to ``slice()`` are translated to a straight C-API call.
* Taking a ``char*`` from a temporary Python string object is safer * Taking a ``char*`` from a temporary Python string object is safer
