2. Each repetition in the transcriber must contain at least one metavariable to
decide how many times to expand it. If multiple metavariables appear in the
same repetition, they must be bound to the same number of fragments. For
instance, `( $( $i:ident ),* ; $( $j:ident ),* ) =>( $( ($i,$j) ),*` must

invoking the macro with `(a, b, c; d, e, f)` is legal and expands to
