+Issues/Omissions
+--------------------------
+The Y combinator function is never defined in this book, I had to copy it out of
+`The Little Schemer`_;
+
+ (define Y
+ (lambda (thing)
+ ((lambda (le)
+ ((lambda (f) (f f))
+ (lambda (f) (le (lambda (x) ((f f) x))))))
+ thing)))
+
+MIT/GNU Scheme doesn't seem to have ``letcc`` or ``try``; I stuck with
+``call-with-current-continuation``:
+
+ (call-with-current-continuation (lambda (hook) ...)
+ ; is the same as
+ (letcc hook (...))
+
+ ; as noted in the book (p. 89)
+ (try x a b)
+ ; is the same as
+ (letcc success
+ (letcc x
+ (success a))
+ b)
+ ; is the same as
+ (call-with-current-continuation
+ (lambda (success)
+ (begin
+ (call-with-current-continuation
+ (lambda (x)
+ (success a)))
+ b)))
