Hi,

I still didnt find good high coverage descriptions/tutorials about how
to write macros in Clojure. I read the stuff in Stuart Halloways book,
thats good, but just a small introduction.

I still have some technical questions, but the main issue seems to be
that I need to dive more deeply into the whole area of macro
programming.

My technical questions:

1. I can use syntax-quote in the REPL, outside of a macro-definition.
Is this of any use? Does this mean the REPL always macroexpands
everything?

user=> (def x 1)
#'user/x
user=> `x
user/x
user=> (+ (eval `x) 3)
4
user=> (+ (eval `(+ 5 ~x)) 3)
9

2. maxroexpand and macroexpand-1 dont extend macros in subforms. Is
there anything that does?

3. Is there a way to use macros in higher order functions? Say along
the lines of

(map def [a b c] [1 2 3])

Btw, am I right that this might be possible in a lazy language?

(probably more to come :)

Thank you, and kind regards, alux
