Hi!
Can one assume anything about the order of grammar actions?
At a given action, can one be sure which action was the previous (just
finished) action?
For example, in case of a list:
list: element {/*action xx*/} | list ',' element {/*action yy*/};
element: A | B | C | D ;
At action yy, is it true (always) that the (immediately) preceding action must
be an action xx or action yy?
In other words: can one action start something and subsequent actions continue and finish it? For example, taking the
list elements one by one, left to right, and appending them to a list (or concatenating to a buffer).
(I am not a list member yet, so please address or Cc to me.)
