1460 /* Function argument lists are arguably the most complex part in the
1461 * parser. They are pretty tricky to understand because of the way
1462 * they are processed, and because of optional arguments that can be
1463 * omitted. When there are several optional arguments in a row,
1464 * omitting one automatically omits all following arguments. Optional
1465 * arguments can only be omitted when either
1467 * a) the omission is explicitly started with \default
1468 * b) the omission is implicitly started by an argument not matching
1469 * its predicate, and there is a mandatory argument later that can
1470 * "catch" the argument that does not fit.
1472 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1473 * (corresponding to mandatory arguments and having a predicate
1474 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1475 * the semantic value of the EXPECT_OPTIONAL token is the default to
1476 * use when the optional argument is omitted, and EXPECT_SCM again has
1477 * the argument predicate as semantic value) in reverse order to the
1478 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1479 * processed inside-out while actual tokens are consumed.
1481 * This means that the argument list tokens determine the actions
1482 * taken as they arrive. The structure of the argument list is known
1483 * to the parser and stored in its parse stack when the first argument
1484 * is being parsed. What the parser does not know is which predicates
1485 * will match and whether or not \default will be appearing in the
1486 * argument list, and where.
1488 * Sequences of 0 or more optional arguments are scanned using either
1489 * function_arglist_backup or function_arglist_nonbackup. The first
1490 * is used when optional arguments are followed by at least one
1491 * mandatory argument: in that case optional arguments may be skipped
1492 * by either a false predicate (in which case the expression will be
1493 * pushed back as one or more tokens, preceded by a BACKUP token) or
1494 * by using \default.
1496 * If optional arguments are at the end of the argument list, they are
1497 * instead scanned using function_arglist_nonbackup: here the only
1498 * manner to enter into skipping of optional arguments is the use of
1501 * The argument list of a normal function call is parsed using
1502 * function_arglist. The part of an argument list before a mandatory
1503 * argument is parsed using function_arglist_optional.
1505 * The difference is that leading optional arguments are scanned using
1506 * function_arglist_nonbackup and function_arglist_backup,
1509 * Most other details are obvious in the rules themselves.
