A low-priority idea.
As suggested by Andrei the D language can disallow naked instructions composed
by a single semicolon:

void main() {
    int x;; // single semicolons not allowed
    goto END;
    END:; // single semicolons not allowed
    // END: {} // OK
}


(D already disallows single semicolons at the end of for statements, etc, so
this can make the language more uniform.)
