C05) How do I work around "Labeled imperative not implemented"?

If you want to write:

(L: Imp1; Imp2; ... Impi :L)

(which is not implemented), you should instead write:

L: (# do Imp1; Imp2; ... Impi #)

In fact, the (L: ... :L) construct is being considered for exclusion from
the BETA language due to the very simple replacement shown above.
