It's not already ticketed, even if the root cause might be the same.
As I pointed out in my message, these are not hash maps, they're array
maps.
You should file a new ticket and refer to #192.

There's a UNIX command called script which records a command line

Thanks for the replies, everyone. I'll look into the clojurebot and
see how that works.
Also, I do understand that this is potentially opening the door to
mis-use of resources, but for now, I'm running in a sufficiently
trusted environment that the benefits outweigh the risks (an OOM or

Thanks for the pointer. Looking into this.

Not exactly what you asked for, but I added a
Excellent summary of each language's sweet spot. I'd like to suggest a
different book for Erlang though.
For learning Erlang, I'd suggest Erlang Programming by Francesco

Clojure and Haskell both include STM systems for controlled access to
shared resources. There's a Haskell distribution known as Glasgow
Distributed Haskell (GdH), which provides facilities for small-scale
distributed programming. Clojure can achieve the same effect through
the use of third-party l

With respect to Stuart's comment above - "Erlang is designed for
distributed operation across many machines; Clojure is designed for a
single machine with many cores.", how are Clojure and Haskell
different? I am just curious to know how do Haskell, Clojure and
Erlang compare.

You might be looking for the instance? function. It can be used to
determine if something is an instance of a particular class.
user=> (instance? java.lang.Integer 5)
true
user=> (instance? java.lang.Integer "5")
false
To apply that to a data structure, you'd need to walk your structure

Hmm, it is what I'm looking for.Just the way I planned it to be. The next
issue now is on how to craft it into clojure.

I'd recommend an architecture where you utilize ejabberd and create
bots/components that read XML stanzas and react. That way you can just
scale your application servers separately and use any language you
choose. You also get chat for free.

Is there a comparison about the speed of local concurrency of Clojure

I find that I tend to name struct instances like the struct. For instance,
