+           - The only way there can be no lookahead present (in tok) is
+             if this state is a consistent state with a default action.
+             Thus, detecting the absence of a lookahead is sufficient to
+             determine that there is no unexpected or expected token to
+             report.  In that case, just report a simple "syntax error".
+           - Don't assume there isn't a lookahead just because this
+             state is a consistent state with a default action.  There
+             might have been a previous inconsistent state, consistent
+             state with a non-default action, or user semantic action
+             that manipulated yychar.  (However, yychar is currently out
+             of scope during semantic actions.)
+           - Of course, the expected token list depends on states to
+             have correct lookahead information, and it depends on the
+             parser not to perform extra reductions after fetching a
+             lookahead from the scanner and before detecting a syntax
+             error.  Thus, state merging (from LALR or IELR) and default
+             reductions corrupt the expected token list.  However, the
+             list is correct for canonical LR with one exception: it
+             will still contain any token that will not be accepted due
+             to an error action in a later state.
