Its a pretty amazing artifact, a complete app with perfect
documentation. Its also essentially a template.
If someone is totally lost on how to get started with clojure web
programming, just go to that.
In the more general case, I strongly agree that
Sorry, I was not precise enough. I meant why is this pattern not used in
all of *clojure.core*.
Every function that takes a variable number of arguments could use it but I
only saw it in the mentioned cases.

Hmm well my library dj kinda relies on the whole dynamic features of

I was quite surprised when this turned out to be the cause of a bug in a

their implementation and in their behavior that a vector and a list

I'd have thought that vectors are eval'd sequentially, are they not?
FWIW I get the same kind of slowdown measurement between versions when
just employing the built-in time macro... will report back after the
profiling session, but it all seems v. odd!

Hi Andy, the timings were collected with two litte macros I've written
and which are available here:

The actual project in question will be released in the next few
months, once things are more stable.

I'm not aware of what changes made in 1.4 could cause this performance
degradation.
Out of curiosity, are you willing to share your code for performance profiling
of future Clojure versions? i.e. is it open source already and so that
wouldn't be a problem, or is it closed source?
Have you run

My guess is that it's useful in the core functions which are more
heavily used. Otherwise you're getting into premature optimization if
you use it in any of your own functions without profiling it first.

That is because dispatch on argument count is fast, while apply is slow.
Especially so since it might have to create an intermediate seq.
It's a performance optimization.

Hey,
When browsing through clojure.core I noticed something peculiar in the
implementation of comp, juxt and partial.
All three share the same implementation pattern. They define separate methods
for the arity of 0,1,2,3 and any.
For example in juxt:

I'm not sure how/if the following would fit your use case exactly, but you
might want to explore the get-in function (and assoc-in, the clojure.walk
namespace and the zippers functionality. They all make dealing with such
deeply nested structures easier.
