fn* is a compiler intrinsic...it's pretty low-level, it doesn't
support destructuring,. So instead, core.clj creates a macro called fn
that adds all this other functionality and eventually spits out the
fn* in a format the compiler wants. Basically it's set up this way so
that you can write the maj
Recently, when looking into the clojure source code, core.clj in
particular,
I found multiple occurrence of 'fn*' instead of 'fn'.
Can anyone help explain what fn* is and the difference between fn and fn*
Thanks

A quick comment on item 13 in the release.
I think that this sort causes some code that I have to fail.
The reason is that the code in question inserts js scripts into the header
of the page - when bootstrap loads.
Subsequent modules require this js to be present - but do not "depend" on
it.

Awesome, I've been looking forward to this release.
The new release has made it out to the upstream maven repository. I just
pushed out lein-cljsbuild 0.1.4, which has the new 0.0-1006 dependency (as

No, clojure-mode determines indentation exclusively from static

I haven't tried yet, but lein-cljsbuild [1] is meant to support

The project I envision would consist of multiple completely independent

The reason for that is:

Hey All,
I'm trying to print the numbers 0-99 as fast as possible. In python,
this

In clojure, even with type hints, this is slow

Here's a slightly shorter variant.

Here's a version with reduce. It returns your elements as sets, but you could
easily (map seq ,,,) if you really need lists.
user=> (reduce (fn [r e] (if ((last r) e) (conj r #{e}) (update-in r [(dec
(count r))] conj e))) [#{}] [1 2 2 3 4 4 1 6])
