https://docs.perl6.org/type/Pair says "Colon pairs can be chained without a comma to create a List of Pairs. Depending on context you may have to be explicit when assigning colon lists." - and follows with examples, which led me to experiments, that raise more questions. I would think all 5 of these should say the same thing but instead give 3 different answers. Does the doc need an addition to describe this? Is it a problem with Rakudo Star 2018.10?
$ perl6 To exit type 'exit' or '^D' > (:a1:b2:c3) (a1 => True b2 => 1 c3 => 1) > (:a1,:b2,:c3) (a1 => True b2 => True c3 => True) > :a1,:b2,:c3 (a1 => True b2 => True c3 => True) > :a1:b2:c3 a1 => True > :a1 :b2 :c3 a1 => True -y
