Using "PyArray_DIMS" with quotes but without parentheses would indeed be 
confusing to users and difficult to implement, so "PyArray_DIMS(*)" 
where the * is TBD seem nicer.

It sounds like the jury is still out. In order to compare the solutions, 
I will move forward with the @property decorator syntax, but to keep it 
simple I will start small: only getters and specifically for 
CFuncDefNodes. Then if you still want to look at the other option I will 
turn my "experiment into a PR.
