Note however, that I seem to have forgotten when and unless. also: cond has no
support for the extended "test guard => lambda" form. Neither do I believe that
the any "special" case form is supported. If there is any interest whatsoever,
I can implement it when I have time.
The code produced is NOT the same as guile3 does for internal defines, however.
(define a 2)
(define b 3)
(display "hej")
(define c 3)
(+ a b c)
becomes ONE letrec under gulie3, whereas my library turns it into
(letrec ((a 2) (b 3))
(display "hej")
(letrec ((c 3))
(+ a b c)))
That should be an easy fix, again if there is any interest.
