I don't know about the whole idea but if we can have versions of
of map, grep, keys and values that returns interators that are built
in perl and returns iterators, the missing thing would a mecanism
to stop releasing a stream (in python, js and ruby, there are both return
and yield but AFAIK all of them lack the ability for the caller to put a
value back in the stream).

Any step toward those built in iterators can obsolete Perlude which
would be nice! Is there any way I can help on that?

regards,
