&gt; &gt; Personally I think that it should be language-independent so modules

&gt; &gt;
&gt; &gt; I kinda like the Self object model (but not the syntax of the language).
&gt; &gt; See <A  HREF="http://self.smli.com/">http://self.smli.com/</A> for info.
&gt;
&gt; Self has pretty 'heavy' objects.  Instead of class concepts there are
&gt; prototype objects.  It has been done in ColdC.  IMO, if the Self
&gt; model was sufficient, there would have been no desire or need for
&gt; Cold's $frob construct.


I personally feel that the frob datatype (in addition to being fairly hard
for most people learning ColdC to learn) is fairly well mis-understood.  It
is closest to being the way to implement abstract datatypes, where you want
all method calls regarding that data to be routed to a particular object.
It is also highly useful, because of the method handler, for implementing
proxies for remote objects.  It is currently used as a lightweight object in
some code, which isn't really where its strength is.

The syntax for a literal frob is:  &lt;object, data, handler&gt; where the handler
is optional.  With a frob without a handler, any call made get transformed:
frob.method(args) =&gt; object.method(data, args)   ....  While this looks
fairly, odd, it has uses within the structure of Cold.  Where it gets
interesting is when there is a method handler, the call gets transformed
like this:  frob.method(args) -&gt; object.handler(data, method, args) ... With
this, you could have something like so:

&lt;$distributor, #[['object, $blah], ['home_system, "ice.cold.org:1150"]],
'proxy_handler&gt;, so that any calls made on that frob would get transmitted
over the network by the $distributor object.

The method handler could also possibly provide some agent-oriented
programming capabilities, but that is probably a bit of a stretch.

BTW, MOO has something similar that someone was working with (not in a
released server, but has been mentioned on MOO-Cows) in the WAIF datatype
(<A  HREF="http://www.tcp.com/~ben/MOO/waif-progman.html">http://www.tcp.com/~ben/MOO/waif-progman.html</A>).
