Two questions have arisen.  Both of these are in connection with
statement labels and gotos, which I know will irritate many; these
questions are raised in connection with certain types of programs
in which the use of goto-less code must be less efficient.

Question 1.  Is there a quick way of using a variable label?
The way it would be used is to identify the label to which one
wants to transfer, and then have some other place or places 
transfer to that point?  Transfers, loads, and stores take a
significant part of the running time of the algorithm, and
so something like setjmp and longjmp are to be avoided.

Question 2.  Is there a way of declaring "local", so that
labels in one block of a coding unit can be the same as
labels in another?  The labels are within the block only,
but the various blocks are connected with gotos, not calls.
