Dear list members,
There is a small problem with unicode escapes in Clojure strings. When
StringReader encounters a unicode escape it checks Character.isDigit
which is only true for decimal digits, but not hexadecimal.
The other problem is that CharacterReader accepts a character constant

Thanks very much. I'll read these change logs for the SVN versions
from now on!
The README for the swank-clojure project recommends using the SVN
version of Clojure, otherwise I'd stick with the regular releases. The
README should probably be modified to point to release 1088.

I'd recommend you use SVN version 1088 instead.
Here are the last few change log

Thank you for your replies,
I wrote the numeric code myself. It's heavily optimized for speed, and
as such, it doesn't contain many explicit matrix multiplications and/
or inversions. All calculations have been expanded to minimize the
instruction count.

Hi Rich,
Wow, that's a comprehensive answer. Thanks.
I am using runonce to create lancet, a build system that ties into
Java's Ant. Build steps definitely do have side effects, so I will
probably end up using the agent approach. Targets don't have (or
ignore) return values, so I could igno

Dear vimming Clojurians,
Gorilla v1.0.0 is released. It is the successor of Chimp. Contrary
to Chimp it uses a network connection for communication with Clojure.
This makes things possible like a Repl in a Vim buffer, docstrings
in a balloon popups or arglists in the command completion.

Hi folks,
I've put together a unit testing library that borrows ideas from
Ruby's RSpec and Haskell's Quickcheck. In Fact, you define a series of
facts that are verified by predicates. These predicates are tested
many times with sequences of data.
A "fact" takes the form:

Yes, it is a StringBuilder so technically yes. I guess you since the only
thing you ever do with a StringBuilder is produce a string it just seemed
like
it would be a string. Same goes for StringBuffer.

Type predicates do an exact match on the type, StringBuilder is a
different class altogether. Why should it return true on a
StringBuilder?

Wouldn't it be a StringBuilder, and not a String?

as briefly mentioned on IRC, I've uploaded a patch to the files-

You should be able to do this without the ref. Have the agent's state

May I ask if you wrote the Java numerics code yourself or whether you
used an existing library instead?
