Re: Is there a way to use Object.factory with templated classes? Or some way to construct templated classes given RTTI of an instance?

Sorry for a technical aside, but would this be something for 
you?

I mean... In either case, there is something curious in the 
Extended/Root usage, as they both are bound to the same type. 
And if so, you could get rid of the templatization in the 
Extended class, either by templating Root on the Extended or 
use the T of Root in Extended.

Perhaps it's half some form of unintended neural network 
fabrication that happened as I wrote the example and half that 
the original code isn't that well thought out yet.  The original 
code looks more like this:

template Nodes(T)
{
        class Root
        {
                T x;
        }

        class Extended : Root
        {
                T y;
        }
}

I will probably end up going with the latter suggestion and have 
Extended use the Root's T.  That would probably make sense for 
what I'm doing.  In my case, the T allows the caller to configure 
what kind of output the thing provides... IIRC (it's been a while 
since I touched this code o.O).

Thanks for pointing that out.
