Can every feature of Gambit be accessed from Jazz code?
Yes. Jazz has a new ‘gambit’ library that can be imported to gain access to every Gambit procedure from Jazz code. As an example: (library my-lib jazz (import (gambit)) (define (test) (let ((vec (f64vector 2.0 3.2 4.6))) (pp (fl> (f64vector-ref vec 2) 1.0)))) (test)) Note that many of those functions are already exported from the ‘jazz’ library. Most have the same name, but some have a different name as their underlying code tries to be portable accross Scheme implementations, mainly Gambit, Chicken, PLT and Bigloo.
