Well, yeah, function spaces are an example of vector spaces: https://en.wikipedia.org/wiki/Vector_space#Function_spaces

Yeah, and it's such a boring thing to write about.

Given an vector space V with (+, ), you can define the vector space over functions F whose codomain is V and where F.+ and F. both take two functions as argument and return another function applying V.+ or V.* on the result. All the linear algebra properties come from the original vector space. Hence it is boring.

* is used on HN for italic delimiters, you need to escape it with a backslash to avoid that.
