Nice explanation :)

This is one of the fantastic (and scary) things I often experience
in this (scheme-y) context (take SICP, or the Little Schemer).
Everything looks so easy, but whenever I try myself, I realise that
I've been taken along a path along high mountains, with breathtaking
views, and down there it gets messy and there are crocodiles.
It takes a long time to massage one's messy, lowly programs into a
form which approaches that deep beauty.
But it's fun :)
