That would be cool except for sometimes the init() function needs to be
called after some assignments. Consider the following example
<cfset server.myVar = createObject("component","foo")/>
<cfset server.thing = handleToSomething>
<cfset server.startupip = "192.168.1.11">
<cfset server.init()/>
if "thing" and "startupip" had resources that the object needed, and the
init() was called without those being assigned, the object could blowup.

I'm curious. Can anyone explain to me why createObject() isn't enough to
instantiate the object? I mean, why it is that <cfset server.myVar.init()/>
would even be required here? It seems to me like the init() could just as
well be an assumed part of a constructor for the object/cfc/etc... And
better still because it would be less code and less prone to screw-ups that
way.
