Log Message:
Update to Clojure 1.8.0

1 New and Improved Features

1.1 Direct Linking

Direct linking can be enabled with -Dclojure.compiler.direct-linking=true

Direct linking allows functions compiled with direct linking on to make direct \ 
static method calls to most other functions, instead of going through the var \ 
and the Fn object. This can enable further optimization by the jit, at a cost in \ 
dynamism. In particular, directly-linked calls will not see redefinitions.

With this change, clojure.core itself is compiled with direct linking and \ 
therefore other namespaces cannot redefine core fns and have those redefinitions \ 
seen by core code.

A new metadata key ^:redef is provided. A function declared with this key can be \ 
redefined and will never be direct linked. Also, functions declared as ^:dynamic \ 
will never be direct linked.

1.2 String Functions

Several new string functions were added to clojure.string to increase \ 
portability and reduce the need for Java interop calls:

index-of - search for the index of a char or string in a string

last-index-of - search for the index of a char or string backwards in a string

starts-with? - true if string starts with a substring

ends-with? - true if string ends with a substring

includes? - true if string includes a substring

1.3 Socket Server and REPL

The Clojure runtime now has the ability to start a socket server at \ 
initialization based on system properties. One expected use for this is serving \ 
a socket-based REPL, but it also has many other potential uses for dynamically \ 
adding server capability to existing programs without code changes.

A socket server will be started for each JVM system property like \ 
clojure.server.<server-name>. The value for this property is an edn map \ 
representing the configuration of the socket server with the following \ 
properties:

address - host or address, defaults to loopback
port - positive integer, required
accept - namespaced symbol of function to invoke on socket accept, required
args - sequential collection of args to pass to accept
bind-err - defaults to true, binds *err* to socket out stream
server-daemon - defaults to true, socket server thread doesn't block exit
client-daemon - defaults to true, socket client thread doesn't block exit
Additionally, there is a repl function provided that is slightly customized for \ 
use with the socket server in clojure.core.server/repl.

Following is an example of starting a socket server with a repl listener. This \ 
can be added to any existing Clojure program to allow it to accept external REPL \ 
clients.

-Dclojure.server.repl="{:port 5555 :accept clojure.core.server/repl}"
An example client you can use to connect to this socket repl is telnet:

$ telnet 127.0.0.1 5555
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
user=> (println "hello")
hello
