C API
  TYPES
   OP *(*hook_op_check_stashchange_cb) (pTHX_ OP *op, const char *new_stash, const char *old_stash, void *user_data)
    The type the callbacks need to implement.

  FUNCTIONS
   UV hook_op_check_stashchange (hook_op_check_stashchange_cb cb, void *user_data)
    Register the callback "cb" to be when an opcode is compiled in a
