Scheme
1. Special Forms
(a) define (sugared form) -(define (name parameters) expressions)
This form is equivalent to (define name (lambda (parameters) expressions)).
(b) let -(let bindings body)
Binds the given bindings for the duration of the body. The bindings is a list of (name
value) pairs. The body consists of one or more expressions which are evaluated in order
and the value of last is returned.
Problems
1. Guess the value, then evaluate the expression in scheme. If your guess differs from the actual
output, try desugaring any relevant expressions.
(define (foo x)
(+ x 3))
foo
(foo 5)
(define bar 5)
(define (baz) 5)
bar
baz
