ANN: ClojureScript 1.9.542, spec changes & REPL enhancement

[David Nolen]

ClojureScript, the Clojure compiler that emits JavaScript source code.

README and source code: https://github.com/clojure/clojurescript

Leiningen dependency information:

[org.clojure/clojurescript "1.9.542"]

This release is primarily about staying in sync with the latest changes to spec. It

also includes a small but significant enhancement to REPLs to allow handling multiple forms.

As always, feedback welcome!

## 1.9.542

### Enhancements

* CLJS-1572: REPL doesn't give error for expressions with too many right parentheses

### Changes

* cljs.spec -> cljs.spec.alpha

* CLJS-2013 - Add MapEntry type

* CLJS-2015: Self-host: `defmacro` should return the Var

* CLJS-2017: Upgrade Closure Compiler to latest April 2017 release

### Fixes

* CLJS-485: RegExp flags are being dropped by string/replace

* CLJS-1518: Case macro expansion evaluates expression twice

* CLJS-2024: Self-host: `find-ns-obj` broken for namespaces with 'a' as the first segment

* CLJS-2028: `realized?` throws on LazyTransformer

* CLJS-2010: refer-clojure :rename throws on valid invocations

* CLJS-2007: Whitespace optimizations should respect :main option.

> * CLJS-2013 - Add MapEntry type

This change seems to break plumatic schema, after upgrading I'm getting warnings:

WARNING: ->MapEntry already refers to: cljs.core/->MapEntry being replaced by: schema.core/->MapEntry at ... schema/core.cljs

Plumatic also defines a MapEntry record type which clashes with the core one.

That's just a warning. Is there some deeper breakage that you are observing?

That runtime error doesn't necessarily seem related to the compile time warning. Would need more information.

I'm assuming that is related to this change, but I'll need to investigate more. There's already a merged PR for schema that excludes MapEntry in refer-clojure. I'm hoping that will fix this.
