Maybe I'm missing something, but do mid-level-rules have any sense but a
little comfort for the programmer? The only think I can think about if the
rule constructs something the lexer needs, but as Hans said already actions
and deps in the Lexer are very dangerous and need to be carefully
 constructed.

What keeps you from simply writing the action at the end?
