So, hell. I just don't know any more. Does the following require collection on x, y and t; on x, y and t′; just on t and t′; or heck, on all four??

Le Sigh. It's way too late at night to be thinking about these things...

     z::Γ ⊢ t::Z     z::Γ, x::X, y::Y ⊢ t′::Q
     -----------------------------------------  X,Y ⊳ Z=X×Y
         z::Γ ⊢ (case t of (x,y) ↦ t′)::Q

...and of course I'm an idiot. One collects on the sequents, not the terms...
