In the ClojureScript case, you can do lazy compile time compilation
instead, where the predicate call is really a macro that always
expands into a predicate call but during compile time can check if the
tree needs to be updated. This isn't as lazy as the runtime version
but at least groups of exten

Actually to simply further, instead of wrapping the old DAG tree, it
simply replaces the DAG tree with the compilation step. The
compilation step then makes the new DAG tree and calls it.

If you want, you can be lazy
The alternative to using eval and large code generation that I've seen
is to use the compiled tree of closures approach used by CL-PPCRE. If
the JVM is smart enough, it may do the inlining for you on the hot
code.

I have a question about the presentation.
You mention that you can't achieve the same dispatching performance in
the open case compared to the closed space.
Lets ignore the namespace issue (maybe by restricting ourselves to
only one namespace).
Also lets assume the predicate ordering is solved.
Excellent talk David. This is hitting a programming sweet spot that I've
wanted for a while. I haven't tried prolog, standard ml, haskell, etc. But
jquery was the first tool that clued me into a kind of pattern matching and
predicate dispatch:
$( ".classA .classB#containingId" ).doSomething();

Awesome talk - thanks!
I particularly enjoyed the sign behind you that says "Don't Panic!" - it helped
keep me calm during the hairily complex parts :-)
I really look forward to seeing where you go with this stuff…

Apparently, the ability to annoy the hell out of whoever you try to
share it with.

Arrrgh, and now slideshare wants me to authenticate via FB or a slideshare
account if I want to download the slides, again.
Ok, I've already got a slideshare account, so I'll try to remember the
pass

Slides are on Scribd as well - http://www.scribd.com/doc/62571669
Hello,
I don't have a Facebook account (and don't want to create one), neither have
or want to create a scribd account. Could it be possible to have the slides
available for download without having to authenticate (e.g. slideshare) ?
