2103  Thus, detecting the absence of a lookahead is sufficient to
2104  determine that there is no unexpected or expected token to
2105  report. In that case, just report a simple "syntax error".
2106  - Don't assume there isn't a lookahead just because this state is
2107  a consistent state with a default action. There might have
2108  been a previous inconsistent state, consistent state with a
2109  non-default action, or user semantic action that manipulated
2110  yyla. (However, yyla is currently not documented for users.)
2111  - Of course, the expected token list depends on states to have
2112  correct lookahead information, and it depends on the parser not
2113  to perform extra reductions after fetching a lookahead from the
2114  scanner and before detecting a syntax error. Thus, state merging
2115  (from LALR or IELR) and default reductions corrupt the expected
2116  token list. However, the list is correct for canonical LR with
2117  one exception: it will still contain any token that will not be
2118  accepted due to an error action in a later state.
