Nice, I just got a bit worried it was yet another module someone thought
would be nice, started making and stoped making after getting tired of it.
Since it seems to be ready I'll go for it.

After some thinking while re-reading the stash you put there I'd change my
original three steps to be:
1. Set template type in begin where I untaint all paramters
($c->stash->{view_type} or something)
2. Set template name in controller getting called by URI
3. Set language in the END by appending _$language depinging on member
4. Add .type ($template .= '.tt' if $view_type = 'TT' ) in end depending of
template system so I can have index.tt, index.json, index_se.tt without
changing anything

Is this remotely what you mean or am I on thin ice in deep waters?

Thanks for the quick reply!
