[Stackless] Stackless support generator functions?

I don't know the answer (I assume so), but I do know that channels provide
far more general functionality.  The yeild thing only goes one level deep
into a function call, whereas a channel can pass values from anywhere inside
a computation.

For example you could "linearize" a tree something like this

def preorderToChannel(tree, channel):
      (node, children) = tree
      for child in children:
             preorderToChannel(child, channel)

...then launch preorderToChannel(tree, channel) in its own tasklet.

As I understand it implementing a "preorder generator" using
the "yeild" construct would be much more complicated, unless
you cheated and stashed the result in a list or something first.

Please correct me if I'm wrong...
