It looks a bit confusing...
I mean, for a traditional Cython user it looks like a temporary Python
list is coerced, meaning that a will point to deallocated memory.
Ignoring that issue, what even happens if you reassign a to some other
pointer? Or is that disallowed?
The initial syntax proposed avoids these problems. I understand that
this was probably much easier, OTOH it might be better not to have a
feature rather than having a confusing feature...
