-  - Performance
+  - Repeat, Sequence, Tree
+  - simplify Forest (considerably)
 
-     - Forest: keep() and valid() -- can we do this with states
-       rather than subtrees?

-     - hash Long->long: it's all bogus

-  * pick back up cleaning up end of Parser.java (Reduction)
+  - decent/better error messages
+      - fix the location stuff, it's broken
 
-  - [more] sensible tree-printout
+  - copyright notices
+  - documentation
 
-  - revamp Tib.Block (do it all in the parser using indent/dedent?)

+v1.1
 
-  - more natural phrasing of metagrammar?
   - finalize metagrammar and rdp-op's
-
-  - should Union.add() be there?
-  - should Atom.top() be there?

   - write some grammars
       - Java grammar
       - TeX (math?)
       - URL (RFC)
       - RFC2822 (email message/headers)
+  - clean up the whole Walk situation (?)

+  - serialization of parse tables
 
-  - clean up the whole Walk situation
+  - "ambiguity modulo dropped fragments"?
+       - can this be checked statically?
+       - eliminated statically?

   - "lift" cases:
       - right now I can only lift the last child in a forest...  begs
         the question of what the right representation for Forests is
