Hello,
I have been trying to write a Guile library for 3D motion and I wrote a
‘vector3’ class and added the method ‘*’ for scaling a vector. This works fine
for any scalar, except for ‘-1’. Here is a minimal code example, I am using
Guile 2.0.14 on OS X 10.11.6:
(use-modules (oop goops))

I believe that Guile is doing strength reduction, transforming (* -1 v)
to (- 0 v).
It could be that this is totally the wrong thing. Is (* x 2) -> (+ x x)

In Scheme, strings are sequences of characters. Encoding and decoding
is only needed when going to and from bytes. Guile supports a finite
number of encodings, so in general some en

Only if both addition and multiplication are defined for the type. In a
group-like structure there is only one operation, while ring-like structures
