WebArrays use the normal C array syntax, e.g. int[10], and the size must be known at compile time for stack allocated arrays. Cython doesn’t support variable length arrays from C99. Note that Cython uses array access for pointer dereferencing, as *x is not valid Python syntax, whereas x[0] is. Also, the Python types list, dict, tuple, etc. may ...
