&gt; &gt; Self has pretty 'heavy' objects.  Instead of class concepts there are
&gt; &gt; prototype objects.  It has been done in ColdC.  IMO, if the Self
&gt; &gt; model was sufficient, there would have been no desire or need for
&gt; &gt; Cold's $frob construct.
&gt; 
&gt; I personally feel that the frob datatype (in addition to being fairly hard
&gt; for most people learning ColdC to learn) is fairly well mis-understood.  

I can't disagree with that. 

&gt;It
&gt; is closest to being the way to implement abstract datatypes, where you want
&gt; all method calls regarding that data to be routed to a particular object.
&gt; It is also highly useful, because of the method handler, for implementing
&gt; proxies for remote objects.  It is currently used as a lightweight object in
&gt; some code, which isn't really where its strength is.

A side-effect.  Those preferring a different object model may be 
tempted to use it as such.   I've been told I've been using it wrong,
but it feels so right.  ;)

&gt; The syntax for a literal frob is:  &lt;object, data, handler&gt; where the handler
&gt; is optional.  With a frob without a handler, any call made get transformed:
&gt; frob.method(args) =&gt; object.method(data, args)   ....  While this looks
&gt; fairly, odd, it has uses within the structure of Cold.  Where it gets
&gt; interesting is when there is a method handler, the call gets transformed
&gt; like this:  frob.method(args) -&gt; object.handler(data, method, args) ... With
&gt; this, you could have something like so:
&gt; 
&gt; &lt;$distributor, #[['object, $blah], ['home_system, "ice.cold.org:1150"]],
&gt; 'proxy_handler&gt;

And that's a simple one, Bruce.  A very user-friendly syntax has 
always been one of my design goals.  It would be nice if Cold had a 
fixed-in-stone bytecode model, then maybe someone could use it 
as target for an Objective Rexx compiler, or some such thing. 
A possible release 2 feature? :)
