I'm not involved in the development of this client library - I'm just
glad to see it get started. Many thanks to the folks a basho for

Hello,
I'm just starting to upgrade to 1.3 ( I know, I know I should have
done this before :)
Like many of you, I am using lein, only I'm just starting to update
the dependency list. Clojure contrib seems pretty straight forward and
documented, but for what about libraries that are found on C
Fantastic !!! I'm looking forward to giving this a try. It has
the potential to solve some problems I am currently working on.
so thanks for your efforts.

Question: Do you really need transactions? or is that you just need
conflict resolution?
I ask because many No-SQL datastores support the later which often is
good enough (or even better in my opinion).
For example look at the descrip

I know I can get the meta data using the following form:

{:ns #, :name get, :file "clojure/

Is there a means to get the meta data from the stored function without
using its identifier?

Both lines 1 and 2, shouldn't return meta, because 'meta' only takes
