Hi,
I took a look at clojure when it first came out. I never wrote many
programs with it but spent a few nights reading docs and experimenting with
the repl.
In Rich's most recent talk, Simple Made Easy, he mentioned that clojure
for javascript was built from the ground up using protocols and
Looks like this video is from 2008. I remember going through all the videos
back then. I'm not looking for a basic introduction to lisp like languages.
I'm interested in a description and an explanation of clojure + modern
features such as protocols. For example, Rich said that clojurescript
Hi,
I am trying to understand clojure and found a couple of interesting
things about the core library:
1. core.clj is a gigantic library with more than 400 function
definitions (378 defns and 62 defmacros to be exact). I didn't expect
to find sequence related functions, such as map/reduce in
As I understand it, map is, itself, lazy. Does that mean that using
map to implement these methods would create extra intermediate
structures?
What if often used functions such as map/reduce/filter were macros,
that could 'deforest' (to use Haskell terminology) these intermediate
structures?
I agree with John. For certain applications, the ability to modify
the code while it is running is very useful.
Many language comparisons turn into syntax comparisons. Clojure has
enough interesting concepts (concurrency model, code as data, macros)
that it should be made to stand out.

I am in the same boat. However, even more than type safety, I miss my
IDE giving me the most appropriate options. I often have objects with
many call-backs, it's nice to be able to ctrl+space (in eclipse) and
quickly get a list available methods, pressing enter gives you some
skeleton code.

+1 for this request. I have a question as well, aren't the namespace
bindings stored in one of clojure's concurrency objects? Since the
ability to interact with a running program is one of the features that
sets clojure apart from most other mainstream programming languages,
if more than one
How do I find the arity of a given function?
I can get a list of all name spaces using
(all-ns)
I can get functions within each name space using
(find-ns 'clojure) ; so map find-ns over each value returned by all-ns
(doc fn) gives me a description of the function, and information about
Impressive, source file and line numbers are already included!
I need to better understand reader macro (or where ever # comes from).
Thanks
Be sure to var-quote the function, i.e. don't use (meta print), but
(meta #'print).
