Hi,
I have had need of a sub hash map function and implemented it as follows;
(defn sub-hashmap
Return a sub map of hmap containing the specified keys.
[hmap ks]
(reduce (fn [mm k] (assoc mm k (k hmap))) {} ks))
(sub-hashmap {:a 1 :b 2 :c 3} :a :c)
;= {:c 3, :a 1}
Is there a similar

Let just creates bindings for a lexical scope. They cannot be

Binding and with-local-vars deal with vars, i.e. mutable references.

That's really a matter of conventions. Both work, and you just have to
correctly adjust the call to load :
1st layout :
src/echo/test.clj
src/echo/test/test-part2.clj
Then you'll have (ns echo.test (:load test/test-part2) in
src/echo/test.clj
2d layout:
src/echo/test.clj
src/echo/test-part2.clj
What I see in your example is binding, but I don't see with-local-
vars anywhere. Or did I misunderstand something?
Sorry, I checked the compojure source again and the servlet headers,
cookies, etc are wrapped in a with-servlet-vars macro (rather than
with-local-vars) which just uses let. The
Determining exactly how much memory objects are using is often

If you use the #^{:static true} metadata on a :methods definition in a

In case you were asking how to call a Clojure function from Java

It would perhaps be a lot more inefficient.
From what I can understand, clojure loads the namespace in question
and the actual command to the compiler is write this namespace to

sort of link step. This requires knowledge of other
