Okay, what about

receive
    .... %% nomal clauses
    Msg ->
        plain_fsm:handle(State, Msg, Fun_that_handles_non_system_messages)
end;

It's a little ugly, but maybe not too much.

Introducing parse_transforms (and maybe lexer_transforms) on a more regular
basis is a cool idea, and interesting stuff might come out of it - but it's no
longer matching the title of the topic "for beginners and purists" ;-)
