seems a great work on array Lloda , for Guile , i can not use it directly in Scheme+ because i search portable code compatible with Racket too (and any scheme that support SRFI 105 curly infix), but perhaps there is not a lot of work to port it , indeed your library seems very powerful ,make me thing of Numpy arrays in pythons. Thanks again. Damien
