1585 * they are processed, and because of optional arguments that can be
1586 * omitted. When there are several optional arguments in a row,
1587 * omitting one automatically omits all following arguments. Optional
1588 * arguments can only be omitted when either
1590 * a) the omission is explicitly started with \default
1591 * b) the omission is implicitly started by an argument not matching
1592 * its predicate, and there is a mandatory argument later that can
1593 * "catch" the argument that does not fit.
1595 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1596 * (corresponding to mandatory arguments and having a predicate
1597 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1598 * the semantic value of the EXPECT_OPTIONAL token is the default to
1599 * use when the optional argument is omitted, and EXPECT_SCM again has
1600 * the argument predicate as semantic value) in reverse order to the
1601 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1602 * processed inside-out while actual tokens are consumed.
1604 * This means that the argument list tokens determine the actions
1605 * taken as they arrive. The structure of the argument list is known
1606 * to the parser and stored in its parse stack when the first argument
1607 * is being parsed. What the parser does not know is which predicates
1608 * will match and whether or not \default will be appearing in the
1609 * argument list, and where.
1611 * Sequences of 0 or more optional arguments are scanned using either
1612 * function_arglist_backup or function_arglist_nonbackup. The first
1613 * is used when optional arguments are followed by at least one
1614 * mandatory argument: in that case optional arguments may be skipped
1615 * by either a false predicate (in which case the expression will be
1616 * pushed back as one or more tokens, preceded by a BACKUP token) or
1617 * by using \default.
1619 * If optional arguments are at the end of the argument list, they are
1620 * instead scanned using function_arglist_nonbackup: here the only
1621 * manner to enter into skipping of optional arguments is the use of
1624 * The argument list of a normal function call is parsed using
1625 * function_arglist. The part of an argument list before a mandatory
1626 * argument is parsed using function_arglist_optional.
1628 * The difference is that leading optional arguments are scanned using
1629 * function_arglist_nonbackup and function_arglist_backup,
1632 * Most other details are obvious in the rules themselves.
