An interesting feature.  But even in C++ I can't see it working correctly, what
with construction/destruction of objects that go into/out of scope to consider.
 In D, this would apply to scope objects in the same way.

Remember that D supports goto only as a concession to programmers who want to
break the rules of structured programming for efficiency reasons.  I think it
goes without saying that the onus is on any D compiler writer who chooses to
add such a feature as computed goto to figure out how to get all this working.

What next - somebody decides to create D extensions for writing self-modifying
code?
