You haven't missed anything. My point was that "the pieces are all
there" -- as Nick pointed out by the rewriting, 'foo is just a
convenient read syntax for (quote foo), so there's nothing special or
new about `',foo, it's still manipulating a list structure in a way the
manual describes.

I'm sure you can find more resources on the net, as the same notation is
used in other Lisps, in particular Common Lisp and Scheme.

(And by the way, if you really find ' and ` "barely distinguishable",
perhaps you might consider using another font? It's an important
distinction to make, as you've now found. ;-))
