Macro stakker::lazy

macro_rules! lazy {
    ( $($x:tt)+ ) => { ... };
}

Lazily perform an actor call or inline code

The call syntax accepted is identical to the call! macro. However the plain [actor], ... form is not accepted because a Core reference is always needed. This queues calls to the lazy queue which is run only after the normal defer queue has been completely exhausted. This can be used to run something at the end of this batch of processing, for example to flush buffers after accumulating data.

Implemented using Core::lazy, Actor::apply and Actor::apply_prep.
