Source code of rec from SRFI 31

There is an implicit requirement that BODY be list-structured for the resulting lambda form to be valid. More specifically, a lambda must have one or more body expressions, so a valid BODY must be (a syntax object containing) a non-empty list.

It is more clear now then.

#<procedure:toto>

works.

Apparently at least some Schemers around the SRFI 31 era (before my time)

ah ah but i used define-macro (Teach Yourself Scheme in Fixnum Days) in the '90 and it is still in some light scheme implementation.
