Abbreviate printing of some objects

[Malabarba]

Instead of printing as
#object[clojure.core$_PLUS_ 0x4e648e99 "clojure.core$_PLUS_@4e648e99"]
they are now printed as
#function clojure.core/+

That's a welcome change, but it will probably be more valuable if we apply it to eval results in general - by this I mean changing the eval results in case when something returns a var. I mentioning this, because of we update it only in the output there would inconsistency between the output and the eval results.

[Malabarba]

eval results are converted to strings via the print-method method. So they are already affected by this.

Good to know. So, this should probably be out of the out middleware then. I'd normally expect to have only stuff directly related to the middleware there (which prompted my original comment).

Where do you think it could go?
If I create a new file for it, I think I'll have to do some configuring to make sure it's loaded.

[bbatsov]

Not sure actually. My biggest concern is that some people might want to turns off the middleware without the custom printing or vice versa and as it stands - they can't do so.

[Malabarba]

I think I'll put it in a file called print-method.clj outside the middleware directory (since it's actually not a middleware). And I'll define a variable for disabling this.

[bbatsov]

Sounds good.

[Malabarba]

Done. ADded tests and method support

[Malabarba]

Alright if I merge this?

[bbatsov]

Allow me. :-)
