Hmm, I can't find references to "included" anywhere, although I admit I
haven't looked very hard. Where is this stuff (and by that I mean
special methods that are called in certain circumstances) documented? I
only found append_features because it happened to be mentioned in the ri
documentation of "include" - and it's very useful.

Okay, this works. My immediate question is, why? That's not quite POLS.
I started out using the block form, because the stuff I was doing in it
wasn't dynamic. But as soon as I want to start substituting variables
into it, I'm going to be using the string form - and suddenly the
semantics of my code changes. What gives?
