Hi,
I'm having some trouble with existing code after a recent svn update. I
think it must have happened sometime in the last 2 or so weeks, but it
might be slightly longer.
The problematic code can be reduced to this:
user=> (def mylocals ['A (fn [] "foo")])
#=(var user/mylocals)
user=> (defmacro letlocals [locals & body]
(list* 'let (eval locals) body))
nil
user=> mylocals
[A #=(user.fn__4291. "[EMAIL PROTECTED]")]
user=> (letlocals mylocals (A))
java.lang.ExceptionInInitializerError (NO_SOURCE_FILE:0)
java.lang.RuntimeException: java.lang.ClassNotFoundException: user.fn__4291
Now, I realise that the use of such patterns is probably bad form (any
suggestions for a replacement welcome!) but this definitely used to
work, and I don't understand why it doesn't anymore.
First of all, is the breakage intentional?
Secondly, you don't get that last error line with current clojure
builds, that's a local change (the *only* local change, I've not been
messing around) to help me track down the problem:

+ if (e.getCause() instanceof
ExceptionInInitializerError)
+ ((PrintWriter)
RT.ERR.get()).println(((ExceptionInInitializerError)e.getCause()).getException());
stare.set(e);
}
}
It's a terrible hack of course, but
java.lang.ExceptionInInitializerError's toString() method is pretty
useless, unfortunately.
Equally unfortunate is that
java.lang.ClassNotFoundException: user.fn__4291
doesn't make any sense at all to me, as the class clearly exists: I can
call the function via
user=> ((mylocals 1))
"foo"
Any help in figuring this one out is greatly appreciated!
Thanks,
~phil
