1423 /* Function argument lists are arguably the most complex part in the
1424 * parser. They are pretty tricky to understand because of the way
1425 * they are processed, and because of optional arguments that can be
1426 * omitted. When there are several optional arguments in a row,
1427 * omitting one automatically omits all following arguments. Optional
1428 * arguments can only be omitted when either
1430 * a) the omission is explicitly started with \default
1431 * b) the omission is implicitly started by an argument not matching
1432 * its predicate, and there is a mandatory argument later that can
1433 * "catch" the argument that does not fit.
1435 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1436 * (corresponding to mandatory arguments and having a predicate
1437 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1438 * the semantic value of the EXPECT_OPTIONAL token is the default to
1439 * use when the optional argument is omitted, and EXPECT_SCM again has
1440 * the argument predicate as semantic value) in reverse order to the
1441 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1442 * processed inside-out while actual tokens are consumed.
1444 * This means that the argument list tokens determine the actions
1445 * taken as they arrive. The structure of the argument list is known
1446 * to the parser and stored in its parse stack when the first argument
1447 * is being parsed. What the parser does not know is which predicates
1448 * will match and whether or not \default will be appearing in the
1449 * argument list, and where.
1451 * Sequences of 0 or more optional arguments are scanned using either
1452 * function_arglist_backup or function_arglist_nonbackup. The first
1453 * is used when optional arguments are followed by at least one
1454 * mandatory argument: in that case optional arguments may be skipped
1455 * by either a false predicate (in which case the expression will be
1456 * pushed back as one or more tokens, preceded by a BACKUP token) or
1457 * by using \default.
1459 * If optional arguments are at the end of the argument list, they are
1460 * instead scanned using function_arglist_nonbackup: here the only
1461 * manner to enter into skipping of optional arguments is the use of
1464 * The argument list of a normal function call is parsed using
1465 * function_arglist. The part of an argument list before a mandatory
1466 * argument is parsed using function_arglist_optional.
1468 * The difference is that leading optional arguments are scanned using
1469 * function_arglist_nonbackup and function_arglist_backup,
1472 * Most other details are obvious in the rules themselves.
