Hi everybody,
form consistency point of view, I totally agree with Juha's suggestion -
go for a C-like language and use break only for switch and return for
exiting the routes.
on the other hand, I worry about backward compatibility - the change
will have quite an impact - and SER compatibility (SER scripts will not
work on OpenSER).
IMHO we should go for a middle stage (as Daniel suggested): the syntax
will accept break outside switch, but generating a warning and
converting it internally to return(1); break will be normally accepted
in switches.
regards,
bogdan

since the language is changing anyway, why not introduce "return" that
returns from a route block and then use break to beak from switch and
possibly other statements you come up with. then semantics would be the
same as in c.
this is an option, too. But I am afraid that some users will be scared
when they will see that compatibility is broken and they will not
easily test the development version using their old config file. Maybe
a intermediary version that display warnings at startup that 'break'
is obsolete and will be dropped soon in favor of 'return' would be
better;
'esac' seems more appropriate to avoid more mess up between 'break'
and 'sbreak'.
