Well, these comments more general in nature; hope that's OK...

I find Clojure's default error messages to be noisy, ugly, and hard to
decipher.  What I'd like is a short, clear explanation of the problem
and a way to get the details, if desired.


Ben Schneiderman gives a lot of good advice on error messages in

  "Designing the User Interface"
  http://www.amazon.com/dp/0201694972

The second edition of the book includes this table (8.1):

  Error-Message Guidelines

    * Be as specific and precise as possible.

    * Be constructive: indicate what needs to be done.

    * Use a positive tone: avoid condemnation.

    * Choose user-centered phrasing.

    * Consider multiple levels of messages.

    * Keep consistent grammatical form, terminology,
      and abbreviations.

    * Keep consistent visual form and placement.

The book (economically available from Amazon) covers each point
in detail.  This might provide useful criteria for any rework.
