tokens because there are none.
- The only way there can be no lookahead present (in yyla) 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
yyla. (However, yyla is currently not documented for users.)
- 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.
