Lets play a guessing game. See who can guess:
- How many occurrences of the identifier 'car' there are in the PLT tree (when using 'read' and just counting the symbols that come out)?
- Where does 'car' rank on the list of the most commonly used identifiers?
- What is the most common identifier, and how many occurrences of it are there?
((define 25294) (quote 24101) (lambda 18883) (let 14796) (send 14349) (x 11877) (if 11118) (... 8474) (car 7610) (syntax 6537))The identifier cdr ranks 21st with 5,259 occurrences, let* has 3,066 which, when combined with let comes out at 17,862, still not enough to pass lambda. Speaking of combining, λ has 2,271 occurrences, which is also not enough to move lambda. Finally map comes in 32nd with 3,853 occurrences and foldl beats out foldr (1168th place with 75 occurrences vs 1451st place with 58 occurrences).
