Holy shit thank you so much. Works perfectly now.
Understood completely wrong what forward_return did.
Thought it alters parameters, but in fact it alters the return value.
So it is not possible to on-the-fly-change a forward's parameters?
That somehow sucks, but thank god it is possible in ham sandwich module.
I'd give you karma, but wow the system was removed? Too many flipping
idiots begging for it? Oh well, thanks either way - it's the thought that counts. =)
