* Why this works (or: how jumping works):
* Jumping means to overwrite the "obj" variable of the loop and set it to the
* target (i.e. the corresponding ELSE or ENDIF). After that, the for-loop does
* the rest: as regularly, "obj" is being updated to point to obj->next, so
* object parsing continues right after the corresponding ELSE or ENDIF. This
* means that if we find an ELSE, it's corresponding IF must not have jumped,
* so we need to jump always. If we encounter an ENDIF, it's corresponding IF
* or ELSE has not jumped, and there is nothing to do.
