No criticism intended Per: as I said, I like Qexo. It might help in
debugging occasionally, I suppose, were the print representation of
list(1,2,3,4) different from that of the container generated by the 
Qexo expression <list>1 2 3 4</list> . Certainly, it was noticing that
my Kawa-supplied lists got displayed as <list> ... </list> by the TLI,
that made me think they were and that this was a Kawa/Qexo special.

Yes, that seems good. I presume that more experience is gained, you'll be
designing and adding features that make it easy to pass data from one
language to the other, and operate on it even if it doesn't
"naturally" belong there. As you've done with Kawa and Java.
