+* ANTLR should issue a warning if you have protected rules and

+* Have a look at the doc's.

+
+* Look more at exception handling

+
+  ANTLR with STL Port. Changing the EOF define to char_traits<char>::eof()
+  breaks things for gcc-2.95.2. Fix this in next release portably.

+* Fix heterogeneous AST stuff. It boils down to adding a method to AST
+  types that knows how to duplicate the sucker.
+  -> done clone() added.
+  Knowing one factory is not enough.
+  -> done in C++ have a superfactory.
+  Also look at having to set the astfactory by hand (this is not 100% necessary).
+  Double check generated code.

+  See my mailbox.. and these comments from Ross Bencina:

+
+* in action.g (java and C++) ##.initialize / ##->initialize is not
+  recognized as an assigment to the root node. In the case ## is followed
+  by ./-> initialize transInfo.assignToRoot should be set to true.
+  Report by Matthew Ford (12 march 2001)
+
+* Add TokenLabelType option for generated lexers. Hmmm can already set token
+  factory. Then again.. you may run into a cast fest..
+
+* Fix some #line counting oddities (Mike Barnett)

+
+* This one triggers a bug in antlr's codegen.
+  #perform_action = #( create_tau_ast(#p1->getLine(),#p1->getColumn()), #p1 );
+
+  #p1 are replaced by p1 in stead of p1_AST. It's really time to rewrite this
+  mess.
+
+  Workaround:
+
+  RefModest_AST tau = create_tau_ast(#p1->getLine(),#p1->getColumn());
+  #perform_action = #( tau, #p1 );
+
+* Unicode and related.
+  - The patch from Jean-Daniel Fekete is an approach. But has some issues.
+  + It is probably necessary to discern an 'internal' string/char type and
+    'external' ones. The external ones are for the lexer input. The
+        'internal ones' are for standard antlr error messages etc. Translators
+        from external to internal should be provided.
+        Hmm on second thought.. probably not really an issue.
+  + What should the lexer read?
+    - Unicode units from a 'unicode reader' in a sense this unicode reader
+      is a lexer itself. Just reading iconv/iconv_open manpages.. Maybe we
+      can hide this with iconv in the InputBuffer mechanisms?
+        - Interpret unicode ourselves. Ugh don't want to think of that right now.
+          we probably redo something that has been done. Only problem is that we
+               need something that's portable (C++ case)
+  + What changes are necessary in the rest of the code to support a wide
+    character set? Think most should be handled in/below the lexer level.
