+- Warn when left-recursive symbols appear elsewhere, other than at the end
+  of a production.  Might have to special-case Newlines.
+- parser not to get into ERROR infinite loop
+- sort 'virtual' symbols to end
+- allow $xy instead of $3.  Chooses shortest bodysym with xy in that order
+    $xy_2 gives the second one
+- allow $TERM terminals to be listed.  If so, extras are errors

 - array buffer - can be added to and grows.
 - char, string search, regexp search
 
 - allow "do stuff" as a stand-alone statement (scope)
+- 'use' labels *must* appear in case statements.
+- re-read parsergen lit-doc and make sure it is still coherent.
