Hi,
That seems to cause me a core dump.
scott@dell:~$ guile
guile> (load "/usr/local/src/guile-scmutils/src/load.scm")
guile> +
#<primitive-generic +>
guile> (module-use! (current-module) generic-environment)
#f
guile> +
#<procedure g:+ args>
guile> (+ 2 3)
5
guile> (+ (vector 5 6) (vector 7 8))
Segmentation fault (core dumped)
scott@dell:~$
Here is how it is designed to work:
scott@dell:~$ guile
guile> (load "/usr/local/src/guile-scmutils/src/load.scm")
guile> +
#<primitive-generic +>
guile> (+ (vector 2 3) (vector 5 6))
Backtrace:
In current input:
3: 0* [+ {#(2 3)} #(5 6)]
<unnamed port>:3:1: In procedure + in expression (+ (vector 2 3) (vector 5 6)):
<unnamed port>:3:1: Wrong type argument in position 1: #(2 3)
ABORT: (wrong-type-arg)
guile> (set-current-module generic-environment)
#<directory (guile-user) b7bd75e0>
guile> +
#<procedure g:+ args>
guile> (+ (vector 2 3) (vector 5 6))
#(7 9)
guile>
and what I'd really like to do is find a way to effectively execute the
(set-current-module generic-environment)
command before the user gets the guile prompt. I'll keep trying things, and let you know if something works.
What puzzles me is that if I just put code in my .guile file to define the things I want, like
(define + g:+)
(define * g:*)
etc.,
I begin to get strange stack overflows, and what appear to be infinite loops. I conclude that the underlying primitive operations are needed somewhere by some procedure. The whole thing is pretty treacherous, I guess. Thanks for your ideas.
Scott

That should be something like:
(module-use! (current-module) generic-environment)
`use-modules' is just syntactic sugar that does this.
Let us know if it solves you problem.
Thanks,
