- I know this, but almost all modern lisps are CL and Scheme (and your
- delightful but obscure favourite, ISO Lisp/TELOS). I have this old habit
- of thinking of Lisp as 1.5 and descendants... I tend to think of
- lexically scoped Lisps as of descendants of Scheme (well, yes, to me CL
- is a huge fat Scheme dialect ;->).

-
- I.e. labels for reference values (they are labels for the 'address' of a
- memory location or a register').
