  LOL. I did say I don't want to open up this Pandora box now ;-).
I'll leave this for you and Rod, he for example thinks that task-base
is in perfect shape ;-).

  Yeah! And we should add Prolog interpreter to do those inferences!
No, Prolog sucks, let's add Lisp. Let's do some AI in OE!

  Seriously, why don't we leave that for some new year and clean up
real dirtiness now and polish frontyard instead?

  And if you ask for discussion, then I hope idea behind the irony
above is clear: all that would add entities without real necessity and
our ability to handle them. What was the aim of task-base
introduction? To build images both full-featured and efficient in
terms size. Does this work? Yes, and as pointed out by Koen, we actually
should start to look for bigger inefficiencies as the image content
list is already not too bad.
