Re: trace-forms macro
Fine, I merged the new version and I will add a couple of tests related to these changes.

tools.trace (was Re: trace-forms macro on the clojure mailing list)
Hi, First shot of tools.trace is now available on github: http://github.com/clojure/tools.trace As for the traceforms macro, you will notice that when an exception is trapped, I recompose an new exception with the necessary form traceback information instead of using print. The main reason is that I want the form traceback to stay close to the exception message. Otherwise if you run several threads writing to stdout, you may end up with split outputs on standard output (the exception message in one spot and the form traceback elsewhere) Comments/suggestions are welcomed. The README.MD is on its way and I still need to review the code to see if they are remaining rough edges. Nothing beats a paper output and a coffee... I expect to work on the build process next week-end and get the first version out next week. Time to go to bed, my eyes are now useless ... Luc P.

Re: trace-forms macro
I am moving the trace contrib stuff to 1.3. I would like to include your trace-forms macro in it. Feeling ok with this ? Comments ? Sounds good to me. After all, I sent it to this list so that others could make use of it! When it comes to issues, in 1.3 it's not allowed to recur across (try ...), which means that the macro wont work with (loop (recur ...)) or (fn ... (recur ...)). Also, the big missing thing is that (trace-special-form) doesn't cover fn*, i.e. the body of functions wont be traced.

Fine, I will have a closer look at the issues you mentioned. I'll repost here when the code is available so you can have a look at it.
