  • TODO create CI build template for C or Fortran code to be used with Numba
• WIP overload_classmethod (PR #7050) and Array._allocate API

  @overload_classmethod(types.Array, "_allocate")
  def _ol_array_allocate(cls, allocsize, dtype):
      # allocsize [int]: bytes to allocate
      # dtype [type]: data type; mostly 
      def impl(cls, allocsize, dtype):
          ...
      return impl

  • Stuart suggested to use item-count instead of num-of-bytes
