I get why asynchronous execution and time-outs are useful, but 
why do you want a time-out that results in the entire program 
crashing? To me it looks like you'd want a function returning a 
Nullable!T which is null in case of a time out, instead of a 
`noreturn` function which is guaranteed to always fail.

So does your proposal fit in this DIP?
