Unlike C++, the language disallows unsafe jumping forward (or is it dmd
that disallows it?). Hmmm... Maybe I am wrong... (?) I swear, the
following code used to generate a compilation error:
if (aCondition) {
goto label; // Jumps over s's constructor call
}
auto s = S(7);
label:
s.foo();
The error used to say:
"Error: cannot goto forward into different try block level."
The code is allowed by dmd 2.059.
The code is allowed for classes as well but of course there is a
segmentation faault due to foo() on the null object. Strange...

I agree.
