Me too :)

Here is my first perverted take on it, which pushes the LUObject 
madness in new uncharted territories...

In a nutshell, I'm thinking to add two new methods to the root LOObject:

(1) anObject.spawn( aMethod )
(2) anObject.yield()

(1) is the equivalent of the good, old VMS's DCL "spawn" command:

http://www.nis.com/volume_1/spawn.html

spawn() is simply a cover method to wrap 'aMethod' into a coroutine and 
register it with LUTask.

(2) is a cover method as well to transparently invoke coroutine.yield( 
this() )

Now any LUObject should be able to play nicely in the weird but 
wonderful world of coroutines without concerning themselves too much 
about what coroutines are in the first place, beside remembering to 
call "yield" when appropriate that is...

LUTask should take care of all the mundanities related to effectively 
creating coroutine and keeping track of them. In other words, LUTask 
not only acts as a wrapper around all the coroutine functionality but 
also serves as a sort of default "run loop" for them along the lines of 
what the "dispatcher" function does in PIL 9.4 - Non-Preemptive 
Multithreading.

Thoughts?
