 #### All `'cdef'` definitions are optional, but they contribute to the speed-up:

 ```python
 cdef <ctype/type> [*]<var_name> [= <obj>]
-cdef <ctype>[n_elements] <var_name> [= <coll_of_nums>]
+cdef <ctype>[n_items] <array_name> [= <coll_of_nums/structs>]
+cdef <ctype> *<array_name> = <<ctype> *> malloc(n_items * sizeof(<ctype>))
 cdef <ctype/type/void> <func_name>(<ctype/type> [*]<arg_name>): ...
