This document is for me to use during, and to distribute after, a lecture at Manchester's Xaverian College, where I'm very honoured to be able to help introduce some core concepts in functional programming, in my role as STEM Ambassador.

I'm writing it in draft mode in public, as a sort of experiment. Feedback gratefully accepted!
