The midterm will take place over the weekend of April 30--May 1.
It will be due before class time on Tuesday 3; extensions till
before class time on Thursday May 5 may be considered.

If you cannot take the midterm on this weekend due to travel or
conflicts with other hard midterms, there will be a make-up
midterm variant offered the _next_ weekend.

The midterm will be open-shell, open-book, open-Internet, as
discussed in class today.

The topics will include:

1. The x86 computation model; functions and scopes
    in compiled C code; the ABI and calling conventions.

2. Functional programming in LISP:
     - "loop-less" style of functional programming,
         recursive traversals of lists and trees;
     - accumulator-style recursive functions and
        tail-recursion
     - tail-recursive optimization vs stack exhaustion
   See OnLisp 2.7-8, 4.3, and 5.5-6 (also, 15.2-3 for macros).

3. Lexical binding vs dynamic binding (based on ELISP).

4. Ruby: the bytecode and VM execution model.
