[killme2008]

Using slime-macroexpand-all to fully macroexpand the expression at point by:

C c M m

But occurred an exception:

 Can't dynamically bind non-dynamic var: clojure.contrib.macro-utils/macro-symbols
 [Thrown class java.lang.IllegalStateException]

It seems that swank-clojure uses clojure.contrib,and some variable could not be bound in clojure 1.3 since they are not dynamic.
