Homework 5 has been corrected as follows.

• If two lambda expressions are compared, the result should be a lambda expression, not a λ expression. (As before, a λ expression should result from comparing two λ expressions, or from comparing a λ expression and a lambda expression.)
• The test case result for (expr-compare '((lambda (lambda) (+ lambda if (f lambda))) 3) '((lambda (if) (+ if if (f λ))) 3)) has been corrected to start with '((lambda' instead of with '((λ'.
• The last test case's last line has been corrected has been corrected to start with '(lambda' instead of with '(λ'.

• Create your SEASnet account and then check that it works as soon as you can, as there are occasionally delays before your account is activated.
• Here are suggestions if you're interested in the course but are neither enrolled nor on the waiting list.
  • Read Enrollment in Undergraduate Computer Science Classes and follow its advice.
  • Any PTEs are not typically given out until the end of the second week, to make sure that enough resources are available. You can try coming to classes before then. Sign up on any attendance sheet that is being passed around.
