That looks exactly right to me. I'll be adopting that.
On further review, I think this is better:

I like that.
In case folks haven't seen them, there are some more functions that

Hi Stuart,
I like the concept very much.
I had a couple of problems in working with the patch:

Currently the compiler writes classes to the hierarchy under the value
of *compile-path* whose root binding is classes.
As we see in Stuart's build.xml patch, it can convenient to be able to
specify such a path as part of the JVM's environment.
To support that, I suggest the following:

You can also make it a little shorter by importing

I think Clojure should change to allow (bigdec 3) to succeed.
BigDecimal has a valueOf method that accepts a long. It has a
constructor that accepts an int. I haven't made a bug report on this
yet, but here it is.
Here are another thing that came up during testing of numbers:

SVN version 1110 of Clojure made a breaking change to a feature that
swank-clojure is using. For now, I recommend moving back one rev by
using:
svn up -r 1109

In the past, Jeff has updated swank-clojure very quickly on those rare
occasions where
