it's much easier to learn Fan. Fan's grammar's semantics is really
clear(its kernel is *only 200 lines *without comments), and we
provide a graphic module to *visualize the tree structure*...
Anyway you can still use Fan* without sticking to Fan's parsing tech*, the
only thing you need is to accept the proposal* which introduces a
Intermediate Ast*
