1576 * they are processed, and because of optional arguments that can be
1577 * omitted. When there are several optional arguments in a row,
1578 * omitting one automatically omits all following arguments. Optional
1579 * arguments can only be omitted when either
1581 * a) the omission is explicitly started with \default
1582 * b) the omission is implicitly started by an argument not matching
1583 * its predicate, and there is a mandatory argument later that can
1584 * "catch" the argument that does not fit.
1586 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1587 * (corresponding to mandatory arguments and having a predicate
1588 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1589 * the semantic value of the EXPECT_OPTIONAL token is the default to
1590 * use when the optional argument is omitted, and EXPECT_SCM again has
1591 * the argument predicate as semantic value) in reverse order to the
1592 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1593 * processed inside-out while actual tokens are consumed.
1595 * This means that the argument list tokens determine the actions
1596 * taken as they arrive. The structure of the argument list is known
1597 * to the parser and stored in its parse stack when the first argument
1598 * is being parsed. What the parser does not know is which predicates
1599 * will match and whether or not \default will be appearing in the
1600 * argument list, and where.
1602 * Sequences of 0 or more optional arguments are scanned using either
1603 * function_arglist_backup or function_arglist_nonbackup. The first
1604 * is used when optional arguments are followed by at least one
1605 * mandatory argument: in that case optional arguments may be skipped
1606 * by either a false predicate (in which case the expression will be
1607 * pushed back as one or more tokens, preceded by a BACKUP token) or
1608 * by using \default.
1610 * If optional arguments are at the end of the argument list, they are
1611 * instead scanned using function_arglist_nonbackup: here the only
1612 * manner to enter into skipping of optional arguments is the use of
1615 * The argument list of a normal function call is parsed using
1616 * function_arglist. The part of an argument list before a mandatory
1617 * argument is parsed using function_arglist_optional.
1619 * The difference is that leading optional arguments are scanned using
1620 * function_arglist_nonbackup and function_arglist_backup,
1623 * Most other details are obvious in the rules themselves.
