The car function takes a List cell as argument, and
returns the contents of the car field:
Stack: "a" "d" cons Stack: <cons> car Stack: "a"
Modern languages often use more logical names like
head or first for this function.
Historical note: car stands for "Contents of Address
Register", referring to the machine instruction used to
implement this in the first Lisp, on an IBM 704 at MIT in
the late 1950s.)
