Re: [ANN] Clojure 1.10.0-beta7
For those keeping score at home, the CLJ-2436 patch says, (defn- typeref->class - [typeref classloader] + ^Class [typeref classloader] (if (class? typeref) typeref - (clojure.lang.RT/classForName (typename typeref) false classloader))) +(clojure.lang.RT/classForName (typename typeref) false classloader))) I was wondering why the compiler required the type hint. It reminded me of something I had seen in the news recently, regarding ClojureScript. The ClojureScript changes.md lists "CLJS-1997: Outward function type hint propagation". That issue, in turn, has an informative comment (Thanks, Mike Fikes!) about *Clojure*: Bronsa helpfully pointed out in Slack that outward type hint propagation is avoided in Clojure because it breaks things like: (defn foo [] 1) (defn bar [] (String/valueOf (foo))) (defn foo [] "foo") (bar) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Thanks for the pointer! My mistake was looking for this in the source-- had I ack'd over the doc/ directory I would have found it!

I'll add that I knew this, but it took me longer than I expected to actually find the documentation to point to. I don't know how a new user of the library would be expected to discover what that symbol means.

Re: Confused by a bit of syntax-- Clojure(script) or Hiccup?
:> is a valid Clojure keyword, but has no special meaning on its own. In Reagent's version of the Hiccup DSL, :> introduces a Reagent component defined from a React component https://github.com/reagent-project/reagent/blob/master/doc/InteropWithReact.md#creating-reagent-components-from-react-components On Tue, Nov 20, 2018 at 11:27 AM Randy J.

Re: [ANN] Clojure 1.10.0-beta7
That is new code in reflect.java so that's a good catch. Patched in https://dev.clojure.org/jira/browse/CLJ-2436 and will prob get that in next.
