Cool, if only that macro could expand to function which detects in runtime
if one of argument which being matched is seq or vec and call proper routine
which is applying :seq or leaving matching expression as for random access.
This is just higher level automation, it doesn't breake core
Hello everybody,
I was playing with core.match library and I notice the following behavior
let [x {:a 1 :b 2 :c 10 :d 30}]
(match [x]
[({:a _ :b _ :c _ :d _} :only [:a :b :c :d])] :a-1
[({:a _ :b 2} :only [:a :b])] :a0
[{:a 1 :c _}] :a1
please excuse the mistake in the namespace in the subject line... it should
have been

If I remove the line [{:a 1 :c _}] :a1 it returns :a-1 .. So, I guess it
means that the behavior is undefined if there are multiple matches.

Hi,
Well many will agree that if you can find a good solution to this
problem this is going to be usefull. I tend to agree too.
The question is maybe can you find a good solution? My response would
be no.
Let me explain: From a theoretical point of view you can always
translate one turring
I *think* this is because when there are multiple matches, the most
specialized matches and 1 is less generic than _

core.clj currently contains two definitions of =, one of which is commented
out. The active one has this docstring:
Equality. Returns true if x equals y, false if not. Same as
Java x.equals(y) except it also works for nil, and compares
numbers and collections in a type-independent manner.

Several improvements have been made to the ClojureScript REPL.
In ClojureScript, the method of printing output will be different for

I ran into an interesting problem while porting appengine-magic to

The Google App Engine SDK uses checked exceptions on many of its API
methods. In many cases, I want to catch these exceptions and do
something Clojure-friendly with them. With Clojure 1.2.x, I had no

eval does work at macro expansion time, but only where it is actually
possible to evaluate the expression its given with only the
information available at macro expansion time at hand.
One case where there is not enough information -- and a minimal Can't
eval locals example -- is the following:
I believe the actual problem comes from things like RT.classForName(),
which internally catches a ClassNotFoundException, and then does this:
throw Util.runtimeException(e);
That ends up just sort of obscuring what the exception is, and you
can't just catch ClassNotFoundException

Just add:
[org.clojure/tools.trace 0.7.1]

This should be a straight replacement for clojure.contrib.trace in your code.
