Patch clj-1093-fix-empty-record-literal-patch-v2.txt dated Mar 13, 2013 is identical to Bronsa's patch 001-fix-empty-record-literal.patch dated Oct 24, 2012, except that it applies cleanly to latest master. I'm not sure why the older patch doesn't but git doesn't like something about it.

Got the following REPL interaction:

% java -jar ~/.m2/repository/org/clojure/clojure/1.5.0/clojure-1.5.0.jar
user=> (defrecord a [])
user.a
user=> (a.)
#user.a{}
user=> #user.a{}
{}
#user.a[]
{}

This should be reopened or declined for another reason than reproducability.

I just checked, and the problem still exists for records with no arguments:

Clojure 1.6.0-master-SNAPSHOT
user=> (defrecord a [])
user.a
user=> #user.a[]
{}

Admittedly it's an edge case and I see little usage for no-arguments records, but I think it should be addressed aswell since the current behaviour is not what one would expect

Unable to reproduce this bug on latest version of master. Most likely fixed by some of the recent changes to data literal readers.

Marking Not-Approved.
