Clojure doesn't give you direct access to the name of the function you're
defining. However, you could use a macro to get that. Here’s one way.
This macro binds the strange symbol %0 to the symbol naming the current
function
In Bash I use the following construct:
printf ${FUNCNAME} needs an expression\n
In this way I do not have to change the print statement when the name of
the function changes. Is something like this also possible in clojure?

You received this message because you
to use the function name in the throw. So that when I change
the function name to round-long, I do not need to change the throw
statement, because the name of the function is automatically filled.

Unless I'm mistaken, in the output you show:
Exception ERROR: round [:high|:low|:normal] VALUE user/round
(repl-startup.clj:30)
user/round is the name of the function, as desired.

Ah, I see. I don't know how to do that. But, the function name should be in
the stack trace associated with the exception. Is there a particular reason
you also want to put it in the message?

Well if I enter in the REPL
Well, one of the many reasons, that clojure is faster than bash is, that
during compilation, code is divorced from the original source symbols.
That means you can only access information about the original source that
you, or some library code you use, put in there for you.
Jony stated correctly,
Clojure doesn't give you direct access to the name of the function you're
defining. However, you could use a macro to get that. Here’s one way. This
macro binds the strange symbol %0 to the symbol naming the current function.
;; %0 is bound to the function's symbolic name within
:
printf ${FUNCNAME} needs an expression\n

You are right: I was not looking correctly
Is there a special variable that holds the name of the currently
running function so it can be output in a logging message?
I'm thinking of something like this:
(defn my-function []
(println entered *current-function*)
...
)

you might already have this way ... but probably only during debug since it
throws an exception and parses it.
http://forums.sun.com/thread.jspa?threadID=548409start=0
that page also mentions something that sounds better:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/StackTraceElement.html
such a var by updating its value on every function entry
would be prohibitively expensive in runtime in the general case.
As e mentioned, it's possible to use the exception system to get the
name of the current function in a particular case.
Here's an example:
[debug_utils.clj]
(ns
[clojure.contrib.str-utils :only (re-sub)]))
(defn unmangle
Given the name of a class that implements a Clojure function,
returns
the function's name in Clojure. Note: If the true Clojure function
name
contains any underscores (a rare occurrence), the unmangled name will
contain hyphens
