A lambda-expression can be used to create an ``anonymous'' function (literally, one without a name); in general, a lambda-expression can be used where a function name is expected. The format of a lambda-expression is:
(lambda (args) code)A lambda-expression is ``quoted'' using the special form function, which can be abbreviated as #'.
(apply (function (lambda (x y) (+ x y)))
'(2 3))
(apply #'(lambda (x y) (+ x y))
'(2 3))
function or #' is analogous to quote or ', but is
used instead of quote for lambda-expressions or function names.
