Nobody here suggested designing D *to* make it more difficult for future D
compiler writers to implement anything.  The point is that D has been designed
to have initialisations and RAII, and as a side effect it is difficult to
implement assigned/computed gotos.

Sacrificing these useful features just to make it easier to implement such a
feature that will be rarely used (not least because of the inherent
unportability resulting from leaving it to third-party extensions) would be
silly.
