Thanks, Khaled.
I realize the limitations etc.--just thought I'd note that these things
are in some measure possible, if one wishes to implement them (not that
one 'should', necessarily). In particular with regards to some recent

And if you look at the rendered output, is there a single

It's not given that that's the only conceivable application. But even if it is,
that's plenty useful in and of itself.
