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
are half way from scheme's vectors and scheme's list, perheaps the
confusion is coming from that)
