196 | /* Some tokens that only appear in expressions must be enabled for | |
197 | states other than EXPRESSION, since parser lookahead means they | |
198 | must be recognised before the parser switches the lexer out of | |
199 | SCRIPT or WILD state into EXPRESSION state. | |
200 | ||
201 | This sort of thing happens for example with NAME in ldgram.y | |
202 | "section" rule, which is immediately followed by ldlex_expression. | |
203 | However, if you follow the grammar from "sec_or_group_p1" you see | |
204 | "assignment" appearing in "statement_anywhere". Now, | |
205 | "assignment" also has NAME as its first token, just like | |
206 | "section". So the parser can't know whether it is in the | |
207 | "section" or the "assignment" rule until it has scanned the next | |
208 | token to find an assignment operator. Thus the next token after | |
209 | NAME in the "section" rule may be lexed before the lexer is | |
210 | switched to EXPRESSION state, and there are quite a number of | |
211 | optional components. The first token in all those components | |
212 | must be able to be lexed in SCRIPT state, as well as the | |
213 | assignment operators. In fact, due to "opt_exp_with_type", | |
214 | anything that can appear on the left hand side of "exp" might | |
215 | need to be lexed in SCRIPT state. | |
