I thought of scannerless parsing, but the input is UTF8 encoded,
which makes using Ulex all the more convenient and less error-prone.
Anyway, I was looking at Dypgen's early actions, and an idea
occurred to me: I can create dummy empty actions that simply
change a global "parsing context" variable:
inline:
| (...)
| BEGIN_VERB enter_verb RAW END_VERB exit_verb {Ast.Verbatim $3}
| (...)
enter_verb: /* empty */ {Global.context := Global.Verbatim}
exit_verb: /* empty */ {Global.context := Global.General}
Still hackish, but better than creating a state machine...
Cheers,
