hehe not reinvent ... I did that for the wheel ;-)
Its just that rebol is a little static when in comes to objects..
I had a lot of "problems" or should I say ... issues... with objects when creating the
glass dialect, and I was tired of having to re-code inits and having to call them after
creating the object. glass has its own private init system. liquid was always part
of the glass design (actually its part of a complete low-level module framework thats
10 years old)... when glass will be at v3 you'll really see new ui concepts (things
like parasites and data based ui descriptions)

not really, if you use attach/quiet it does not actually call a notification... but you
could call a notification... since the object already is allocated when parsing the dialect
right?

of course !

ok. I've done fancy styles (like a vid blocking menu system) but I'll need just a few
clarifications on this one (if you have time):
> Style Text Text with [

does the value at the end of "make block!" really matter i.e. could it be 1? is it similar
to:
[words: copy []]
> insert insert tail words 'attach func [new args] [
new is sort of like "self", but on the newly allocated face, right?
I guess args points to the word block at the first argument word (ptr to a notifer,
for example),
> new/attach args/2
> next args
and this return the list past all arguments you need... :-)

this is PAINLESS indeed,
Steel v1 will already be easier to use :-)
thanks a lot,
