Ok, I see what you mean, namely that the concept of a 'label' is that it is an
optional component of the 'loop' statement, and not a statement in its own right.
Fair enough, I'll stay within that boundary (for now).


Do the parsing rules mean that this below would be valid ...

while 1 label :top: do

In other words, the symbol used to name a label can contain any character except
whitespace and cannot start with either a digit or '#' or '--'. So it would be
okay (if not a bit over-the-top) to have ...

while true
     label &&MAIN-PROCESSING-BLOCK: 
   do
     . . . 
   end while
