Suppose that I evaluate some expression, then later in the program I
want to evaluate some other expression but only of the earlier one
succeeded. What is the most idiomatic way of doing this in Icon? I've
done something along the lines below, but I'm just a little

   e1 & succeeded := 1
   ...
   if \succeeded then e2
