ANN: ClojureScript 0.0-2755, Browser REPL, macros, and incremental compilation

[David Nolen]

ClojureScript, the Clojure compiler that emits JavaScript source code.

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

New release version: 0.0-2755

Leiningen dependency information:

    [org.clojure/clojurescript "0.0-2755"]

This release fixes regressions to the browser REPL that resulted

from the foreign dependencies enhancement.

This release also includes two very big enhancements. The first

is around macros. If your library does the following:

    (ns foo.bar

       (:require-macros foo.bar))

Then users that require your library:

    (ns bar.baz

      (:require [foo.bar :as foo]))

Will get  `foo.bar` macros automatically required and aliased

to `foo`.

The other big enhancement is true incremental compilation

support. While we have had incremental compilation for some time

it has suffered from the fact that we did not recompile dependent

namespaces - this meant no compilation warnings and corrupted builds.

With auto recompilation of dependent namespaces we eliminate

many cases that previously would have required a clean.

Feedback welcome!

### Enhancements

* CLJS-948: simplify macro usage

### Fixes

* CLJS-927: real incremental compilation

* Browser REPL regressions

* CLJS-991: Wrong inference - inconsistent behavior?

* CLJS-993: binding macro returns non-nil with empty body

* CLJS-972: Node.js REPL eats errors in required ns when using require

* CLJS-986: Add :target to the list of build options that should trigger recompilation

* CLJS-976: Node REPL breaks from uncaught exceptions

Just pushed out 0.0-2758. The only change was a fix for the macro usage enhancement.

And just pushed out 0.0-2760 which catches a ns spec parsing regression caught by some helpful people in the ClojureScript IRC channel.
