Your post is nice but does not at all talk about the issue I am presenting.
I know metadata is attached to the form reader reads and not to the evaled
result of that form. My issue is of the evaluation of the metadata map
itself.

Hi list,
Just a thought, I usually limit my usage of (:use) to DSL-like functions,
like for instance cascalog :
(?- (stdout) [?a ?b] (generator : ?a ?b))
Without a use, or (:require :refer :all), this would become very
cumbersome to read :
(cascalog/?- (cascalog/stdout) [?a ?b] (generator
Hi,
my understanding is, that the metadata is evaluated when the literal is
evaluated. In the first case this means to just strip the surrounding
quote. So nothing happens to the metadata. In the second case upon
evaluation the literal vector is traversed and its elements are evaluated.
Hi,
I was just going to post exactly the same. I've looked in the Compiler.java
and the evaluation of metadata happens together with evaluation of the
form. So it is a desired behavior after all.
Regarding empty vector, I've already created a ticket for it,

you are using comparator incorrectly. The function you pass there should
return true, when x is to the left of y when called as (f x y). See the

You could also do (use 'clojure.test) below the ns form. One thing that

It just goes to show that conventions are important.
