[CLJ-1067] Fix error message inconsistencies in Symbol and Keyword

Fri, 1 Mar 2013 12:47:08 -0600

1. There are some ugly and unnecessary – but harmless – inconsistencies between Symbol and Keyword:

(.run 'foo);    => ArityException Wrong number of args (0) passed to: Symbol  clojure.lang.AFn.throwArity (AFn.java:437)
(.run :foo);    => UnsupportedOperationException   clojure.lang.Keyword.run (Keyword.java:97)
(.call 'foo);   => ArityException Wrong number of args (0) passed to: Symbol  clojure.lang.AFn.throwArity (AFn.java:437)
(.call :foo);   => IllegalArgumentException Wrong number of args passed to keyword: :foo  clojure.lang.Keyword.throwArity (Keyword.java:88)
(.invoke 'foo); => ArityException Wrong number of args (0) passed to: Symbol  clojure.lang.AFn.throwArity (AFn.java:437)
(.invoke :foo); => IllegalArgumentException Wrong number of args passed to keyword: :foo  clojure.lang.Keyword.throwArity (Keyword.java:88)

2. Keyword.java contains a lot of code that has already been factored out to AFn.java.

I propose that Keyword is modified to extend AFn to resolve the above issues.
