This will do what you want, but I would not advise using it:
(defmacro def-with-meta [symbol init]
`(let [m# (meta ~init)]
(def ~symbol
No, I'm looking for a copy meta routine.
The mysterious defmeta macro does this, in one call.
(defmeta a map)
(= (meta (var a)) (meta map))

Okay, then I need a hand with something then. I'm trying to come up
with a macro that does the following:
(defmacro def-with-meta ...) -> You supply this
(def-with-meta symbol init)
(= (meta (var symbol)) (meta init)) -> True
Any suggestions folks?

It uses (meta (var common/basic-logger)).

I'm a bit confused by what the doc macro is doing. Doesn't it simply
work of the metadata of what is passed to it?
I try this at the REPL:
user=> (doc common/basic-logger)
-
decorators.common/basic-logger
nil
nil
nil
For the following item:
user=> (meta common/basic-l
