I used to think they are exotic and more complicated than they are.
They just bind identifiers to macro transformers, just like
define-syntax, but with the region of the bindings limited, and their
body is just like begin so it can have defines that get spliced. Take a
look at xitomatl/{alists,define,fuego}.sls for the simple way I've used
let-syntax so far.
