I'm increasingly using nested delegates to partition code.

3. Those referenced stack variables that make up the closure
are allocated on the GC heap, unless:
* The closure is passed to a scope parameter.
* The closure is an initializer for a scope variable.
* The closure is assigned to a scope variable.
I'm generally not storing the delegates or passing them around
as values, so I don't think the thing about scope variables and
parameters *directly* applies.
Am I safe as long as I don't do something like, pass
`&sendThing` as an argument to `std.concurrency.receive`?
Yes.
