Hi,
the first form is idiomatic. This seems to be a problem in emacs.

Hi,
BTW: the linked discussion pre-dates the time when docstring support à la
defn was added to defmulti. Now that it is available, you should use it
just as for defn.

Hello,
weird, I know, but I have keywords in a map like this:
:first/second
I want to convert such a keyword to a string and I'm doing this with the

(name x)
second
(The reason why I have such keywords at all is that

Hi,
keywords can qualified - just as symbols. Compare: :foo, :user/foo, ::foo
(assuming you are in a fresh REPL). You can also use namespace aliases:
(require '[some.name.space :as short]) ::short/foo.

Hey all,
I've separated out the macro magic behind the wonderful
clojure-koanshttps://github.com/functional-koans/clojure-koans into
its own project
(clojure-koan-enginehttps://github.com/functional-koans/clojure-koan-engine),
making it easy for anyone to write koans for any clojure library!
I've added a new ticket http://dev.clojure.org/jira/browse/CLJ-891 to jira
for adding the ability to make (symbol some-ns bar) work. That tackles
half of the issue in #4, and reduces your example to just (symbol *ns*
(name sym)).

Really great. Looking forward to boring everyone with contracts-

Hello,
While I am going through the Programming Clojure 2nd edition book, I
am entering the code into a REPL.
Sometimes when entering the code I enter a typo and hit enter and
cannot get the REPL to close that malformed line.
It often happens with an errant closing ] or ).

You can't store primitives in vars. But you can cast their contents to
primitives with (long ...) (int ...) etc

Not sure if this is what you want, but Clojure 1.3 introduced ^:const.
This lets you store a primitive constant value:

I'm wondering if core.logic can be used to solve equations over reals
or rationals; all the examples I've seen are with with integers and

I'm a third (?) of the way through implementing cKanren which brings
Constraint Logic Programming (CLP) to core.logic. It going a bit slower
than expected since this is not a simple port - I'm making quite a few
representation / efficiency changes. cKanren supports arithmetic w/
integers, CLP(FD).
David:
Very good news. This stuff is awesome as is, but still really excited
to see cKanren in all its optimized glory! Thanks for all your work on
it.

If it helps someone debug this for Don (since he and I discussed this off-list):
The stack trace from ClojureQL originates in its function to return
generated keys and it's calling .getInt on the (generated) key which
fails because it's a UUID.
So the question is probably: why is ClojureQL
