Hello,
As I work through the Programming Clojure book, I play with the code I
enter into the REPL.
I just want to say that I am infinitely enjoying using the REPL in
Counterclockwise. It does make multi-line code so much nicer.
I entered this.

I tried to run sqlitetest project in lein.I get this error
no :main namespace specified in project.clj
Why would i get an error in an example?
I first run lein deps.
Then i run lein run
then comes error??

I noticed in my code that I often nest a let inside an if-let, or vice-
versa, so I wrote a macro let-else that expands into nested lets,
except where there's an :else after a binding, in which case
that binding expands into an if-let.
E.g.
(let-else
[foo (f1) :else (e)
bar (f2)]
(b1)

I've added a little overview in the code, hopefully this should make things
clearer. Also I made parse, the main invocation point, extensible to users
of the library.

You can write anaphora with syntax-case. In fact, defmacro i
I'm migrating some code from 1.2 to 1.3, and one of the things I've

Is there a more compact abbreviation I can use? Where are such things

As David mentioned, *unchecked-math* is documented as a compile-time flag.
The coercion functions are a bit muddled by the changes to primitive math
in 1.3. In Clojure 1.2, you could get primitive int inside loop/recur by
calling `int` in the loop initialization. You can still do that in 1.3, bu
*unchecked-math* is a compiler flag.

The built-in Clojure REPL is bare-bones to minimize external dependencies.
Maybe some day we can have alternate distributions with more full-featured
REPLs. For now, it's easier to use a development environment: Emacs +
inferior-lisp or SLIME, Counterclockwise + Eclipse, Clooj, LaClojure +
