Ok. The 1.0 is on the horizon :) This is good news!

I'd say, post a core-patch as-is on the website,
so people who'd like to use it can grab it from there.
I'm certainly going to try it, as soon as I get some
relief from the current pressure at work.

I'm already perfectly satisfied, but I'm sure 
others would add something to this.

I'm not using relational databases, so I can't
say much about it.

Here I could add a thing :)

I'd like to see some kind of automatic object garbage
collection, for example, when an object gets defined
within a scope of a proc, I'd like it to get auto-destroyed
when this proc exits. 

It could be something like:

Class foo
foo instproc init {args} {
    puts stderr "[self] comming"
    next
} 
foo instproc destroy {args} {
    puts stderr "[self] leaving"
    next
} 
foo instproc test {args} {
    puts "Hallo World"
}
proc dummy {args} {
    foo private fooVar  ; # "private" might be a new constructor method
    $fooVar test
    return
}

When somebody calls "dummy" proc, a new "foo" object gets created
(the "private" method" and automatically destroyed when proc returns.
Can such thing be done with simple Tcl variable traces, hm?

What about:

     o proc m6 {} {
       this set x 123
     }

The "this" command refers to the current object, like [self] does.
