While this would be feasible for these two functions, it wouldn't work
for "caddr" and ilk :-)
I faintly remember discussions back in the early seventies to replace
"car" and "cdr" (which originally stood for "Contents of Address Regis-
ter" and "Contents of Decrement Register", respectively, and referred to
machine instructions on some then modern PDP hardware which were used to
access the two pointers of a cons) with "fst" and "rst" (for "first" and
"rest", respectively) which could even be nicely combined to "frrst" and
similar. But this proposal never made it :-(
Sincerely,
Rainer
