   Now, VAR is nothing more than a ``one-slot CONS''.  GET-VAR is the
   one-slot version of CAR/CDR, and SET-VAR! is the one-slot version of
   SET-CAR!/SET-CDR!.  So, why does it make the language so
   different/unclean?
   ...

The one-slot CONS
Is just a cell.
The two-slot CONS
Makes lists as well.
And I will bet
A coin of bronze
There isn't any
Three-slot CONS.
