I’m sending this in as a rakudo bug because I think it is. We have confusion about what is a Pair and what is a named parameter. I see just about everybody fall into this trap. The only way I see around this, is to separate the meaning of Pair and named parameter visually as well: a => 42 # a Pair :a(42) # a named parameter I could also see going as far as making a named parameter an Enum, or a(nother) subclass of it.
