I just realized this is not an accurate description of what cython.address does, but of what PointerType does instead. I hadn't noticed the [] boxing cython.address does when creating the pointer. So I guess the list case in the PointerType constructor is there just to support this boxed parameter, not lists per se. Nevertheless my main concerns still stand: (i) the boxing won't make cython.address(x) equivalent to &x when x is, say, an int (you get a "pointer to the box", not a "pointer to the int"); (ii) I don't know how to create an instance of ArrayType in a way the compiler likes (and I don't understand the point of doing that, even if it were possible) and (iii) in any case that array will be copied when the PointerType constructor type casts it, so I won't really get a pointer to an array but a new array instead. Sorry for the autoanswering, I'm a bit overwhelmed with my first intimate contact with cython. Any clarifications will be *very much* appreciated. Regards -- Carlos
