Immutable data (e.g. quoted data) - nice but not necessary
Proper line numbers
Make middle neater by using macro matching
More efficient macro matching (regular expression simple and fast) --- Measure performance to see if we need this
Sort out nil vs null discrepancy
Have the bind() call of the reflective environment be something that is called after the environment is initialised, this way when main classes become environments for libraries, we have regularity
eval tail call---can we test this?  ((lambda (x) (eval `(,x ',x))) '(lambda (x) (eval `(,x ',x))))
Java call order, e.g. CLOS is left to right for specialisation
make CallStack not static, for multithreading

own stack: catch exceptions (e.g. ClassCastException)
