I have created a *highly experimental* library for unit-checked math. I
realize that there are some existing solutions, but I wanted something more
lightweight that would layer on top of the existing Clojure/Java numeric
system rather than create a new one. This is designed to provide

default model and so on. I would definitely support merging the efforts on

You will have to import cljs.test and clojure.test conditionally for the
respective platforms. Their APIs are very similar. Some conditionals might
have to be added, depending on your use.

What you wanted here was

It's a little weird but the reader attaches the metadata to the symbol. Then
the quote just evaluates directly to the same symbol, so the metadata is
preserved.
I agree that metadata can be confusing though. Especially around where AND
Hi Sean,
Pedestal's router is just an interceptor in the chain. You could easily
write an interceptor that looks at the request and sees if it can resolve a
var by that name. You could even stack multiple routers - first the var/fn
lookup and failing that, a more explicit router.
Cheers,
From your comments, I suspect this may be a source of confusion as well:
When you have something like (defn ^{:doc Increments} a-fn [x] (+ x 1))
the metadata is attached to the symbol at read time. However, during the
compilation process, the metadata on the symbol is transferred to the Var

Because ' is a reader macro which expands to the list (quote some-symbol),
so the metadata is applied to the list, and not the symbol. You can verify
this in the REPL - (meta (quote ^:abc 'some-symbol))

Hi!
I have some trouble with clojure metadata / reader and I do not know if I'm
doing something wrong.
I have this code:
(defn some-func [])
(def func ^:abc some-func)
(assert (= (meta func) {:abc true}))
(def data [[:bar (with-meta some-func {:abc true})]
[:baz ^:abc some-func]])
When dealing with metadata, it's important to understand the difference
between these two expressions:
^{:foo :bar} baz
(with-meta baz {:foo :bar})
The first expression attaches metadata to the 'baz' symbol at compile time.
The second expression attaches metadata to the data held in

The documentation says very clearly that:
In addition to with-meta, there are a number of reader macros (The Reader:
Macro Characters) for applying metadata to the expression following it:

The documentation is rather misleading, as it implies that obj can be a
symbol. However, because ^ is a reader macro, it is applied to obj before
it is evaluated.
Clojure maps, vectors and sets all evaluate to themselves, so attaching
metadata to the unevaluated expression via the ^ reader macro,
