It is consistent. There is a difference between () and nil. () is the
empty list. However there is no
Should not it be empty colection instead?
It seems odd to me since it is inconsistent and forces to consider one
more case (nil or collection).
And another question. I have written this function

"Make map (f x) -> x"
[f coll]
(reduce #(assoc %1 (f %2) %2) {} coll))

I've done a pass through most of the Clojure programs on the shootout
web site recently, making some of them faster, and choosing -Xmx
command line arguments when running them to keep the memory usage down
to a reasonable level -- not always the smallest heap size that works,
mind you -- ju
I've made a change to the naming and location of AOT-compiled
assemblies generated by ClojureCLR.
Previously, ClojureCLR had followed the conventions of ClojureJVM in
naming/locating class files (assemblies in CLR-land) generated by AOT-

Specifically, in ClojureCLR< property access in CLR interop is treated
in the same way as fields and zero-arity methods.
For class properties, ClassName/PropertyName works.
For instance properties, (.PropertyName instance) or (. instance

Hi All,
I've found extending-protocol to hold on to a references to records when
they're redefined.

(foo [this]))

Thanks for these answers. I forgot about Robert Hooke, although I've
seen it already. I don't have a real use case yet. I'm researching

more and Robert Hooke looks ver
Since defining the UI in Clojure is pretty tedious process, even with

this more easily and in a declarative way. I was inspired by a series

Actually, you should thank hiredman, for adding the original wall-hack-
field. I just wrapped some lipstick around it.

Yes. This is what I implied.

show's a very cool function, but has a different purpose, (afaik).
It displays the structure of an instance, but not it's contents. get-
all-fields displays the contents. For example, if "a" is defined like

And macroexpand (and pr in general) should have an option to mark what is a

Hi,
why don't you just fully qualify the constructor function? Works from
everywhere.

I agree with Shantanu and feel that Ring is a nice example of AO
I think what a Ring middleware[1] does might be very close what you
want to do with AOP. Clojure has a natural way to "decorate" an
existing body of code using higher order functions and macros.

Could you share some use cases that you want to achieve with AOP?
Hi,
Are there any general purpose libraries/frameworks with nice API/DSL
for Aspect Oriented Programming for Clojure? Or is there someone
working on it? Is it needed? Possible?
