I've seen fudged in C/C++ so many times, but that really seem to require native
language support.

Sorry if this has been discussed before, but I'm new here :)

I remember reading something about it some time ago in this forum... I'd like to
have coroutines, too. Yesterday i read some papers about Lua's implementation
regarding coroutines and they seemed quite useful (more than Python's), given
some time to experimente with them. But Lua is interpreted; maybe it's harder to
implement coroutines in languages compiled to machine-code...

It's been discussed before (Aug 2003). Walter expressed interest.

Here's some references (I put this together in a hurry, so you'll need 
to follow some of the links to understand the context):


*Initial suggestion*

*Walter's posts*

"Coroutines are pretty cool. They aren't in D now, but they could be 
added in the future."
http://www.digitalmars.com/drn-bin/wwwnews?D/15345

"I'd like to eventually add coroutines to D, but there are other things 
that need to be done first. If you'd like to do a coroutine class, sort 
of like some of the C++ ones out there, that could become part of 
Phobos. It could hide the portability issues."
http://www.digitalmars.com/drn-bin/wwwnews?D/15361

"I'm going to have to study it a bit. Can you make it work on linux? 
Write a doc file for it?"
http://www.digitalmars.com/drn-bin/wwwnews?D/15374



"I've been reading about fibers on google, but I am not yet convinced 
they are the right solutions for coroutines because:
1) seems like a lot of overhead to manage them
2) not portable"
http://www.digitalmars.com/drn-bin/wwwnews?D/15349


"It sounds like fibers have an ill-designed implementation, and are not 
ready for prime time. Besides, I may have found a neato way to do 
iterators without need of coroutines."
http://www.digitalmars.com/drn-bin/wwwnews?D/15434


"I want to try and implement it first to see if it works. I have my best
ideas when out jogging, including this one. What I like to do is 'load 
up on context', which means do all my research at the computer, with 
this newsgroup, google, my books, etc. Then out the door for a run. I 
think all the pounding seems to throw all the bits of data around in the 
air, shaking them around until they fit together <g>."
