we had a discussion with Volker about this few weeks ago - in my Cython code I
needed to do, as he suggested, a workaround like this:
int* vlamatrix "(int (*)[])" (int*) # a hack to get int (*)[] through cython
This was for 2-dim arrays of variable length, and looks similar to the
stuff here.
IMHO it would be good to address this, too.
I'd rather stick to C99 conventions in Cython.
To me, using '->' for types looks way too close to what is used, with
different semantics, in functional languages like Haskell or Coq.
