Hi Rich, and all,
I took a stab at writing a static compiler class, i.e. a main() that
just compiles all the .clj files on the command line and saves the
.class files. Patch attached.
It almost works. The only thing that seems

Another way to create a map is:
user= (apply hash-map [:a 1 :b 2 :c 3])
{:a 1, :c 3, :b 2}
Yes, that's fine, and for the flatten:
(interleave (keys m) (vals m))

Patch attached. This precompiles everything except parallel.clj,
which requires an extra Jar. It also omits the source .clj files from
the clojure.jar file.

Patch applied (svn 1101) - thanks!

Hi Meikel,
I spent a few minutes trying to write a macro to do this that doesn't
use eval. So far no good. Is it truly impossible, though? I have never
seen a good discussion of things that can be done only with eval.

Some people have asked how to donate to Clojure, so I've turned

We're coming around the other side of the few breaking changes I
wanted to get done before release 1.0.
The changes are:

While setting ns to clojure.zip, I get the following error:

A shorthand version allows the metadata to be a simple symbol or
keyword, in which case it is
treated as a single entry map with a key of :tag and a value of
the symbol provided, e.g.:

Ah, yes. I meant, what are these hints? What does the compiler change?
Is it some sort of informal type enforcement or something?
The hints are described here:

One of the many things that I really like about Clojure is that it
