Since Ken doesn't mention it explicitly: there's a difference between
vec and vector. (vec x) returns a vector containing all the elements
of x - a vector "view" of x, I think the doc mentions. (vector x)
returns a vector containing the single element x.

With programming languages, sometimes it can involve discovering language
n+1 to give some new perspective on language n, and getting the "ah ah"
moment with language n.
