1637 * parser. They are pretty tricky to understand because of the way
1638 * they are processed, and because of optional arguments that can be
1639 * omitted. When there are several optional arguments in a row,
1640 * omitting one automatically omits all following arguments. Optional
1641 * arguments can only be omitted when either
1643 * a) the omission is explicitly started with \default
1644 * b) the omission is implicitly started by an argument not matching
1645 * its predicate, and there is a mandatory argument later that can
1646 * "catch" the argument that does not fit.
1648 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1649 * (corresponding to mandatory arguments and having a predicate
1650 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1651 * the semantic value of the EXPECT_OPTIONAL token is the default to
1652 * use when the optional argument is omitted, and EXPECT_SCM again has
1653 * the argument predicate as semantic value) in reverse order to the
1654 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1655 * processed inside-out while actual tokens are consumed.
1657 * This means that the argument list tokens determine the actions
1658 * taken as they arrive. The structure of the argument list is known
1659 * to the parser and stored in its parse stack when the first argument
1660 * is being parsed. What the parser does not know is which predicates
1661 * will match and whether or not \default will be appearing in the
1662 * argument list, and where.
1664 * Sequences of 0 or more optional arguments are scanned using either
1665 * function_arglist_backup or function_arglist_nonbackup. The first
1666 * is used when optional arguments are followed by at least one
1667 * mandatory argument: in that case optional arguments may be skipped
1668 * by either a false predicate (in which case the expression will be
1669 * pushed back as one or more tokens, preceded by a BACKUP token) or
1670 * by using \default.
1672 * If optional arguments are at the end of the argument list, they are
1673 * instead scanned using function_arglist_nonbackup: here the only
1674 * manner to enter into skipping of optional arguments is the use of
1677 * The argument list of a normal function call is parsed using
1678 * function_arglist. The part of an argument list before a mandatory
1679 * argument is parsed using function_arglist_optional.
1681 * The difference is that leading optional arguments are scanned using
1682 * function_arglist_nonbackup and function_arglist_backup,
1685 * Most other details are obvious in the rules themselves.
