scheme - What parts of R5RS are generally considered not worthwhile to implement? -


i have been looking around good, small scheme implementations. notice usual claim follow "almost all" of r5rs, never of it. parts of r5rs considered hard/not worthwhile? considered mistake of r5rs?

if you're looking things under too-hard/not-worthwhile category, there several tricky details of implementing continuations in various places (and small implementations don't have support real continuations either). take @ (now outdated) chart sisc authors put together: http://sisc-scheme.org/r5rs_pitfall.php systems, while claiming implement "(most) everything", have few overlooked details that.
