1277 /* Function argument lists are arguably the most complex part in the
1278 * parser. They are pretty tricky to understand because of the way
1279 * they are processed, and because of optional arguments that can be
1280 * omitted. When there are several optional arguments in a row,
1281 * omitting one automatically omits all following arguments. Optional
1282 * arguments can only be omitted when either
1284 * a) the omission is explicitly started with \default
1285 * b) the omission is implicitly started by an argument not matching
1286 * its predicate, and there is a mandatory argument later that can
1287 * "catch" the argument that does not fit.
1289 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1290 * (corresponding to mandatory arguments and having a predicate
1291 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1292 * the semantic value of the EXPECT_OPTIONAL token is the default to
1293 * use when the optional argument is omitted, and EXPECT_SCM again has
1294 * the argument predicate as semantic value) in reverse order to the
1295 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1296 * processed inside-out while actual tokens are consumed.
1298 * This means that the argument list tokens determine the actions
1299 * taken as they arrive. The structure of the argument list is known
1300 * to the parser and stored in its parse stack when the first argument
1301 * is being parsed. What the parser does not know is which predicates
1302 * will match and whether or not \default will be appearing in the
1303 * argument list, and where.
1305 * Many of the basic nonterminals used for argument list scanning come
1306 * in a "normal" and a "closed" flavor. A closed expression is one
1307 * that can be parsed without a lookahead token. That makes it
1308 * feasible for an optional argument that may need to be skipped:
1309 * skipping can only be accomplished by pushing back the token into
1310 * the lexer, and that only works when there is no lookahead token.
1312 * Sequences of 0 or more optional arguments are scanned using either
1313 * function_arglist_backup or function_arglist_nonbackup. The first
1314 * is used when optional arguments are followed by at least one
1315 * mandatory argument: in that case optional arguments may be skipped
1316 * by either a false predicate (in which case the expression will be
1317 * pushed back as one or more tokens, preceded by a BACKUP token) or
1318 * by using \default.
1320 * If optional arguments are at the end of the argument list, they are
1321 * instead scanned using function_arglist_nonbackup: here the only
1322 * manner to enter into skipping of optional arguments is the use of
1325 * The argument list of a normal function call is parsed using
1326 * function_arglist. The part of an argument list before a mandatory
1327 * argument is parsed using function_arglist_optional.
1329 * The difference is that leading optional arguments are scanned using
1330 * function_arglist_nonbackup and function_arglist_backup,
1333 * Most other details are obvious in the rules themselves.
