It's gone. The situations where this really makes a difference are
negligible and one has to try relatively hard to break the obvious
(but not 100% correct) implementation which is used in chicken.
The compiler is tuned to the particular expansion used and generates
better code.
The solution is to redefine the `letrec' macro.
