All exceptions that occure in the 'else' part will not be catched by
the 'rescue' clauses of that 'begin'...'end' construct. That is
indicated by requiring that the 'else' clause have to come after *all* 
'rescue' clauses.

So, as you assume codeB will not throw an exception, there is no
difference except that codeB is not potentially protected.

BTW: You said that you would include the

   begin
     :
   end until ...

construct in the FAQ. Will you also document it in the book?
