Baldur added,
Mind sharing how, with this example, please?
Many things would have to change, of course. But the main point would be that into_future() takes a proof objectthat the token is in the future, and the comparison would give you this proof.
Uhm, no, that "into_future()" is to make the (pure, already evaluated) "OK<...>" value into a "Future<...>" value.
Ok, I have no idea what this code does.
But the general idea applies. I'll let @edwinbrady work out the details. 
I'd probably write a test, to be honest...
