I think no other software calls objects "tuples".

What about DrtioContext?
And name the fields, as is usually done.

Slightly related: I like the tuple to keep the argument list shorter/more compartmentalized, should we adapt it in other places too?

Agreed that a a lot of argument lists are needlessly long. Especially with the shared sync primitives theres a lot of repetition. Though I'm not sure that these tuples make things much shorter, without some type aliasing. Is there a case for putting these shared sync prims in a struct and passing around an Rc to that instead? (In a similar style to how the mainline repo passes around Io)

Putting the idea out there, obviously it would be a heavy refactor...
