Eelco Dolstra 04c4bd3624 * Store lists as lists of pointers to values rather than as lists of
values.  This improves sharing and gives another speed up.

  faster than the old evaluator.

Eelco Dolstra ac1e8f40d4 * Use a symbol table to represent identifiers and attribute names
efficiently.  The symbol table ensures that there is only one copy
  of each symbol, thus allowing symbols to be compared efficiently
  using a pointer equality test.
