IMO any decent product should at least fail gracefully and for that
you must have some place at the top catching throwables, even if you
can't recover. So w.r.t. the javadoc in java.lang.Error where it says
[a] reasonable application should not try to catch. I interpret it
as justification for the
Have you look at Scsh?

It's not the most trendy, but being a Scheme at least is nice.
Anyone capable of doing the job properly either won't take any money
or won't come cheap, so you might be better of offering a round of
beer or request bids.

You're not missing anything. In a lisp DSL, the L is a figure of
speech, for it's still lisp. Sure, lisp libraries can have great ease
and convenience as if they came with the language, but it won't be a
different language altogether --i.e., something that it ain't lisp.
Last year I wrote a little
That's the default. You'd usually use the sys env clojure.compile.path
for the repl (on windows):
java -Dclojure.compile.path=.;src;classes -cp clojure.jar clojure.main
Clojure 1.2.0
user= *compile-path*
.;src;classes

Oops -- I got the class and compile paths mixed up. But I wonder why
that worked in the OP.

Real nice and short. Doing [ args] avoids the vector:

{1 {2 {3 {4 {5 6, 7 8}

Dynamic binding is more useful when your function expect the *var* to
change during the program. And sometimes you can't pass arguments
through, like in (run-tests). How about a simple API with this usage:
(set-opt :development) ; this is what you want
...
(get-opt :show-sql) ; need this flag
1. The Clojure wrapper put the last two calls inside the if, unlike
Matcher#replaceFirst(), thus the nil.
public String replaceFirst(String replacement) {
if (replacement == null)
throw new NullPointerException(replacement);
StringBuffer sb = new StringBuffer();
reset();
You need to quote the vector so the date will be created inside eval,
instead of having the date go into eval as an element of the
(evaluated) vector.
user= (eval '[(java.util.Date.)])
