Yeah, me too. I don't know why I suggested it. Another generic solution is to change the bottom tested loop into an infinite loop.

do {
   ...
   next if ...;  # XXX
   ...
   last if ...;  # XXX
   ...
} while cond();

becomes

for (;;) { # for ever
   ...
   next if ...;  # OK
   ...
   last if ...;  # OK
   ...
   last if !cond();
}
