Sure correct fix.
Off topic following.
I'm wondering why this was never used. It seems you are attempting to
have an array of pointers to something. Given however that dynamic size
element are not supported why not instead having a pointer to an array
or even just an array?
Why not having a test for this syntax?
Why we don't use pylint?
$ pylint -E python_modules/ptypes.py
