Next question: If I can make this work, would you be happy to see it

div {

If it's predictable, yes, that would be lovely.
I think it is. That is, we can sequence side effects just fine:
my $x = 0;
div { p { $x++ } p { $x++ } p { $x++ } }
will still output 0/1/2, not 2/1/0.
The trick here is (again) context-driven katamari: Under scalar
context the block is suspended without
actually executing, and the statement-level void context tag takes
care of executing the pending sequence
in order. If you're up for coding it tonight it'd be cool, otherwise
I'll do it over the weekend.
Thanks,
