That depends on how you interpret the word vector, which is
You are interpreting it as "An element in a vector space, often
represented as a coordinate vector" whereas in this case I try to mean
"A one-dimensional array".

The fact that FSVec is internally implemented using lists doesn't
imply that FSVec should be interpreted as a list. FSVec is an ADT and
I could as well have used something else to implement it (inmutable
arrays for instance).
