Re: gak! slib

[Chris Wedgwood <chris@cyphercom.com>]

I know SFA about what I'm talking about, but I decided to try installing
jacal and using the jacal.scm thingie below.

For the most part seemed to work.

[...]


    jacal.scm:
    ----------------------------------------------------------------------
    (define-module (jacal) :use-module (ice-9 slib))
    (define horner #f) ; Workaround for a bug in Jacal
    (slib:load "jacal/math.scm")
    (define-public math math)
    ----------------------------------------------------------------------

    /mdj


I use the above, only after (slib:load "jacal/math.scm") I added (slib:load
"slib/arraymap.scm") - if I don't things fail with "array-map!" being
unbound.

The (define horner #f) also doesn't seem to hold, so I have to do this
manually. Anyhow, playing with the Jacal manual I tried something and things
broke.


So what is the problem here?

P.S. Jacal looks way kewl.... what does work, works really well.
