Hey,
You have too many colons:

I am reading a bunch of clojure files using the build-in reader (or
tools.reader, it has the same problem) and I am running into a problem
regarding namespaced keywords (is that the right term?) such as ::l/test.
= (read-string ::l/test)
RuntimeException Invalid token: ::l/test
The double colon keyword creates a namespaced keyword and is perfectly
valid syntax. It's just not used that often :)
By default a keyword like ::test resolves to the current namespace like
::current-ns/test, but you can also provide another ns which causes the
problem when reading.

A namespace-qualified keyword has a single colon:
:my-namespace/something
The double-colon is only shorthand for the current namespace:
(in-ns 'my-namespace)
::something - :my-namespace/something

Casper, in the example source file you pointed at in the core.logic test
suite, the only times it uses the ::namespace/symbol syntax is where
namespace is an alias for a namespace that has been created by an earlier
:require statement.
In my limited testing in Clojure 1.5.1, that syntax throws an
It is used in test.generative code by Stuart Halloway, which is probably

The double-colon is only shorthand for the current namespace:
Or other namespaces via an alias:
(alias 'clj 'clojure.core)
::clj/foo = :clojure.core/foo
Inside ns forms, the :as keyword creates aliases.
