[Jscheme-user] srfi 45: Primitives for Expressing Iterative Lazy Algorithms

[Ken A. <kan...@bb...>]

A while back, i was playing with lazy evaluation trying to understand monads
and ran into a stack overflow problem that surprised me.  This srfi explains it.
http://srfi.schemers.org/srfi-45/srfi-45.html

It turns out that the Ableson and Sussman book used what's called the "odd" style of lazyness which leads to problems http://mitpress.mit.edu/sicp/.  This is the style i was using.

The "even" style described in the srfi corrects the problem.  And this is what the lazy functional languages use.
