Hello,
maybe of some interest:
Lazy pairs for Guile
http://uucode.com/texts/lazypair/index.html
In my applications, I'd like to represent tree-like structures as
the real Scheme lists to Guile. There are two issues here:
* structures are big enough. Making a full copy of data is overhead,
so I'd like to instantiate tree branches on demand.
* Scheme list functions such as car, cdr, for-each etc should work
on exposed data.
These issues are solved by patching Guile source code. Not the best
way, but it works for me. Comments are appreciated.
Regards, Oleg
