1276 /* Function argument lists are arguably the most complex part in the
1277 * parser. They are pretty tricky to understand because of the way
1278 * they are processed, and because of optional arguments that can be
1279 * omitted. When there are several optional arguments in a row,
1280 * omitting one automatically omits all following arguments. Optional
1281 * arguments can only be omitted when either
1283 * a) the omission is explicitly started with \default
1284 * b) the omission is implicitly started by an argument not matching
1285 * its predicate, and there is a mandatory argument later that can
1286 * "catch" the argument that does not fit.
1288 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1289 * (corresponding to mandatory arguments and having a predicate
1290 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1291 * the semantic value of the EXPECT_OPTIONAL token is the default to
1292 * use when the optional argument is omitted, and EXPECT_SCM again has
1293 * the argument predicate as semantic value) in reverse order to the
1294 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1295 * processed inside-out while actual tokens are consumed.
1297 * This means that the argument list tokens determine the actions
1298 * taken as they arrive. The structure of the argument list is known
1299 * to the parser and stored in its parse stack when the first argument
1300 * is being parsed. What the parser does not know is which predicates
1301 * will match and whether or not \default will be appearing in the
1302 * argument list, and where.
1304 * Many of the basic nonterminals used for argument list scanning come
1305 * in a "normal" and a "closed" flavor. A closed expression is one
1306 * that can be parsed without a lookahead token. That makes it
1307 * feasible for an optional argument that may need to be skipped:
1308 * skipping can only be accomplished by pushing back the token into
1309 * the lexer, and that only works when there is no lookahead token.
1311 * Sequences of 0 or more optional arguments are scanned using either
1312 * function_arglist_backup or function_arglist_nonbackup. The first
1313 * is used when optional arguments are followed by at least one
1314 * mandatory argument: in that case optional arguments may be skipped
1315 * by either a false predicate (in which case the expression will be
1316 * pushed back as one or more tokens, preceded by a BACKUP token) or
1317 * by using \default.
1319 * If optional arguments are at the end of the argument list, they are
1320 * instead scanned using function_arglist_nonbackup: here the only
1321 * manner to enter into skipping of optional arguments is the use of
1324 * The argument list of a normal function call is parsed using
1325 * function_arglist. The part of an argument list before a mandatory
1326 * argument is parsed using function_arglist_optional.
1328 * The difference is that leading optional arguments are scanned using
1329 * function_arglist_nonbackup and function_arglist_backup,
1332 * Most other details are obvious in the rules themselves.
