I have a nested data structure, used by a bunch of functions that presume
knowledge of its structure, and I wonder how to change a part of the
structure in a safe way, preferably in small incremental steps, rather than
having my code broken until I update all the functions and tests for the

How are you accessing the data?
I suppose that if you were accessing (maybe you are) the data via helper
functions, that's where most of the refactoring should happen.

Hi all,
do you know how is possible to add a function result, that is another
function, to a collection, a list for example:
(defn *f1* [msg] (*fn[msg](println (str "hello " msg))*))
(def collection '())
(cons (f1) collection)
in this situation f1 must be of type ISeq to can be added to

this is the problem even if I call correct the function, sorry for that

You have a couple of problems in your code. Let's take it a line at a time:
(defn f1 [msg] (fn [msg] (println (str "hello " msg
Here you have two "msg" arguments. The inner one will override the outer
one. If you want both, they need to be different names. For example:

+1 for open sourcing drcfg!
Might be interesting to apply the same idea (drcfg) to the SS component
model, where a component manages the atoms instead of having to def them. I
did something very similar but on top of Curator. One component defined as
a service discovery component, and others th

That's a simple AXIOM program, but I'm sure one can easily translate it

Hi,
When using tools.analyzer.jvm you have to remember that its primary
use-case is as a front-end for a compiler, in this case :tag and :o-tag
serve to inform tools.emitter.jvm when to emit a cast thus might not
always reflect the :tag meta of the expression :form.
Regarding the :tag/:o-tag diff
