#### 22.3.7.1 Tilde Asterisk: Go-To

The next arg is ignored. `~n*` ignores the next n arguments.

`~:*` backs up in the list of arguments so that the argument last processed will be processed again. `~n:*` backs up n arguments.

When within a `~{` construct (see below), the ignoring (in either direction) is relative to the list of arguments being processed by the iteration.

`~n@*` goes to the nth arg, where 0 means the first one; n defaults to 0, so `~@*` goes back to the first arg. Directives after a `~n@*` will take arguments in sequence beginning with the one gone to. When within a `~{` construct, the “goto” is relative to the list of arguments being processed by the iteration.
