How is it with Lisp, it is dynamically typed, right, and the
values, not variables, have type?
But what's the real definition of type?
(type-of 1) ; integer
(type-of 1.0) ; float
(type-of t) ; symbol
(type-of 'type-of) ; not function, symbol, well, OK
(type-of #'type-of) ; still not function, symbol
(type-of [1 2 3]) ; vector
(type-of "string") ; string
(type-of ?a) ; not char, integer, yes
(type-of '(1 2 3)) ; not list, cons
(type-of nil) ; not list, symbol
(type-of '()) ; same
(type-of (list)) ; ..
... ?
