Well, say you decide that several lines of code should be executed
repeatedly.  You can stick in the while...: , your editor can indent
the block, then you have to hunt for numbered `continue` and `break` and
increment some, but not all of the numbers.  Unnumbered `continue` and
`break` cause similar trouble, but the trouble is guaranteed to be more
local.  For non-local I much prefer the exit-by-exception.
