It is, C and D have more or less the same goto rules.

goto.c:
===
void a() {
         goto cool;
}

void main() {
         a();
         cool: ;
}
===
$ gcc goto.c
goto.c: In function a:
goto.c:2: error: label cool used but not defined



While you can still kinda sorta spaghetti in C, the fact
that it is limited to a function makes it much easier to
follow. There's only one function to look at, not the
whole program.

The requirement of a label is important too, since any
particular line of code can't be a comes-from point;
unless there is a label there, you can be pretty confident
that the line before is actually run before.
