Reusing "break label" syntax with symantic that differ from Java and other languages will confuse much more people. I am speaking about PDM's decision. And C++ hasn't "break label" syntax so nothing to confuse. We already discussed this patch and nobody except Zeev was against it. I am not sure that PHP needs goto and I'll post my new patch to discuss it. Thanks. Dmitry. > > I am already developing real goto patch, that will able to > reuse same > > labels.
