[Kamailio-Devel] Use of goto

[Daniel Corbe]

There are cases where goto makes code more readable not less readable.  Take
nested loops, for example where you need to break out of the outer most loop
from inside the inner most loop.  Currently there are no semantics to do
that cleanly other than using a goto or adding a bunch of arbitrary and
unnecessary logic to determine when you are finished.
