Thinking a bit about it, I guess my (only) constructor:
(defmacro gen-make (&rest body)
"Return a generator that evaluates BODY to generate elements.
(let ((this-element (make-symbol "this-element")))
`(let (,this-element)
(lambda ()
(if (eq ,this-element 'gen-done)
'gen-done
(setq ,this-element (progn ,@body)))))))
is just a special case of Daniel's `lambda-generator':
(defmacro gen-make (expr)
`(lambda-generator ()
(while t (yield ,expr))))
modulo (at least currently) the different kind of termination (right?).
So, all of my stuff can be expressed in terms of Daniels generators.
Which means that it would be a suitable extension to Daniels package,
defining some special generators, the transducers, and the cache, for
his more general kind of generators. It could then be named
"generator-x" or so.
Michael.
