The problem is not only that - the problem is that some constructs
might
be unsafe to jump in. Example - jumping in or out of foreach may be
very problematic with current engine (jumping in may result in crash,
jumping out - in memory leaks). And there can be more such things.
Perl's goto specifically forbids jumping into control structures that
require intialization (for instance, foreach()). That seems like a
sensible limitation to me.
