ribol's Issues

raise-on-all is broken: java.lang.UnsupportedOperationException: nth not supported on this type: Symbol

It looks like raise-on-all always throws an exception:

java.lang.UnsupportedOperationException: nth not supported on this type: Symbol

Using the example from http://z.caudate.me/ribol/#raise-on-all

(manage
 (raise-on-all :error (/ 4 2))
 (on :error []
     (continue :none)))

ExceptionInfo not properly handled by ribol "catch"

Because of the way ribol uses ExceptionInfo objects, other ExceptionInfos are not properly caught when they don't belong to ribol.

> (manage (throw (ex-info "an error" {:my :data}))
    (catch Throwable t t))
;; throws: ExceptionInfo an error  clojure.core/ex-info (core.clj:4403)

I believe the problem is that when ribol catches an ExceptionInfo, if it doesn't belong to ribol it will rethrow it, which doesn't reach the remaining catch clauses in the try block. Perhaps another try block should be wrapped around the first one, where all the parse-try-forms clauses can go?
