Yes, that's why we were already syntacticalizing with the *%foo proposal.

That too.

Seems to me that the * processor could easily install a pair-to-named
promoter if that was deemed to be desirable. The * already says you're
cheating.
Alternately, instead of a normal list composer, have one that generates
a special list that is predigested into zones.
my @args := arglist(1, 2, 3, :foo('bar') <== @slurpme);
baz([EMAIL PROTECTED]); # Just Works
Presumably we need that funny list type anyway to collect named vs
positionals vs slurpies at compile time, so all we need to do is
expose that type via arglist() or whatever we call it. Maybe it's just
my @args := ArgList.new(1, 2, 3, :foo('bar') <== @slurpme);
Doesn't have to be Huffshort.
