FWIW, this follows out of the 1 argument rule:
$ 6 'for { a => 42 } { dd $_ }'
:a(42)
$ 6 'for { a => 42 }, { b => 666 } { dd $_ }'
Hash % = {:a(42)}
Hash % = {:b(666)}
If only 1 argument is specified, it will be iterated over. And you could
consider list assignment also such a case (as it internally calls @x.STORE in
that case).
