Well, Scheme coders can be a little loose w/ the type of return  
values. The way Lisps deal w/ truth values causes consternation for  
people with a different background.

Scheme was considered by some a step forward because it has a  
designated boolean type. But it loosens the definition for truth  
testing; a convenience.

This is an area of debate in comp.lang.scheme, but not by me.

There is a globally optimizing compiler - Stalin. See the "stalin" egg.

Yeah, it isn't right.

Some of the SRFI documents are not up-to-date with respect to the  
reference implementation. This isn't true in general & the more  
recent are probably in-sync.
