| SRFI 127: Lazy Sequences

Sorry as I do not have much to say towards the other SRFI's, as I am
somewhat ignorant as to their process, however I noticed this one and
could only think of the lazy-seq egg by Moritz Heidkamp
(http://wiki.call-cc.org/eggref/4/lazy-seq#author). I've had a lot of
good experience with the egg (although at first I will admit its usage
confused me quite thoroughly).

Nonetheless, I noticed that the SRFI document mentions implementing
lazy sequences in a different way (utilizing SRFI 121: Generators,
which is also on your list). I was wondering if the lazy-seq egg has
been brought up whatsoever regarding this SRFI, and if there's some
difference I'm not seeing here. My understanding is that the lazy-seq
egg wraps the lazy-list in a record type that encapsulates the first
element and the generating expression, but I may be wrong. Other than
being able to use (car lazy-lst) and (cdr lazy-lst) normally, is there
a specific reason for the difference here?

Apologies if this comes off as noise on the list, this is purely my
curiosity speaking.
