Encapusulation of threads is a nonsense idea. Encapsulation is a
compile-time concept that completely disappears at runtime. A thread (a task
or tasklet) is a run-time entity with little compile-time presence. Trying
to encapsulate that makes about as much sense as trying to hide memory
allocation (which also doesn't really work).
In today's environment, one has to keep the threads at the highest possible
level of a program, otherwise you will drown in overhead. Sticking threads
inside of things is exactly opposed to that. I expect that in a future
environment, threads will be assigned by the compiler, and again writing
them explicitly is opposed to that. (And if you're not concerned about
performance, please don't use them at all - the disadvantages outweight any
possible advantages.) I don't see a reasonable scenario where hiding threads
is ever going to be a good idea. It might work on some compilation system,
but it will never be that portable.
Randy.
