Hi Miro!  Glad to have you aboard.  :-)

Let me fetch some stuff from both posts first an then get on about
what I'm attempting to say.

OK, Let me agree that Cold is event driven.  Cold is a generic interactive server.
You are not restricted to programming a mud with it.  The events modeled
within the cold language, because of the application's nature, are "computer"
events.  Objects in the core like $connection, $scheduler, and $event_handler
require a "data processing" view to the application.  There is nothing
wrong with this, it allows great flexibility.

What I am attempting to accomplish is a programmable game server.  The scope
of my core language is limited to objects that are game oriented.  All of the
the objects you mention above have been consigned to the dispatcher as they
have little to do with the "game".  Also all events that take place within visibility
of the interactive mud language are game related and implemented by providing
both syntax constructs and multiple $root classes like $player, $thing, $location 
and game system abstract classes like $help, $table, etc.  Its the bare essentials
on which to build a number of FRPG rules systems on.

The hopeful reasoning behind this is that I don't require builders to be coders
in the traditional sense.  I can build an interactive environment where events and 
objects reside strictly within the problem domain.  Put a "visual" framework
around this interactive programming environment and I hope to have something
that will attract hard-core RPG game players and game masters.
