Allow a binding operation to bind more than one operand at once, exposed as $<_0>, $<_1>, .... A single value remains the common case, but the upcoming SORT COMPARATOR must bind the two elements being compared, so the binding becomes an indexed frame and $<_1> is added. Referencing an index the active binding does not provide is reported as an error. Issue: #27892
