+  - EOF token?

   - foo.add(x)

+      - distinguish Conjunct from Sequence?
+            => !(Conjunct instanceof Reducible)
+  - document the assumption that Sequences that match epsilon
+    must have tag, and that ONLY that tag is returned
+    when the sequence matches epsilon
+  - try to avoid building the parts of the tree that end up getting

+  - double-check all the region logic

-  - evil problems with: (x y? z /ws)
-     - it gets even more evil than that
-     - basically, follow restrictions are not honored when the element

+  - paper/techreport opportunities
+      - interaction between RNGLR and follow restrictions
+      - "doomed node" optimization

+  - serializable parse tables?
+  - better ambiguity reporting
