i agree with you all but there is a misunderstanding of what i'm
currently doing.
I'm not making + that append vectors a part of Scheme+, it is just for
a personal program that i want to overload it. This will never be in
Scheme+. (even if python use + for appending list, and list in python

+1. I'd recommend only implementing a method foo on a type bar if you are in
control of either fo

hello,
is it possible to overload an existing operator in Guile?

for example in Scheme (+ i admit) i can do :

solution:

thank you
i understand i must overload + the usual way in class

about the described problem this should not be a problem because -
