I can't disagree with that, but after learning clojure I realized that I interned `car` and `cdr` as symbols of which I like :

  - the symmetry: 'c[ad]r'
  - thus same size
  - small size (3)

and ended up being annoyed by `first` and `rest`. I see them as APL-like characters now.

ps: based on that, head/tail, hd/tl, fst/snd (seen in ml dialects) are also good candidates.
