Ok, this is how the thing now looks like:


the file is also attached.

This is now a library of higher level stuff for the iterator objects
created by Daniel's generators that were previously included into Emacs.

What I had been named "cache" in the last version - that was a dynamic
cache for the elements returned by an iterator implemented as a delayed
list based on delayed conses - has been reimplemented and is now named
"ilist" - IteratorLIST.

These are delayed lists as well, but built from normal conses, that
(can) reference an iterator to produce "more elements" on request.  I
chose this approach because I think it suits much better the nature of
Emacs Lisp.

You can convert from/to lists and iterators, and some functions to work
with ilists are included as well.

Dunno yet how useful this stuff is, at least I need it personally.

We could put this to Gnu Elpa if Emacs Dev is interested; else, I'll put
it on Melpa.
