Did I miss this in the spec somewhere? I've basically assked the same
question in regards to file tests. I wouldn't be asking the question if
the spec didn't keep talking about pairs and adverbs being the same
thing. If the Pair and adverbs aren't different syntax for the same
thing, how should that affect that chart in S02?

Could you have :16('deadbeef')? Should the :8(377) still work (so, does
'wrong' mean it won't do what I'm thinking it will do, or that it does
mean that Perl 6 won't compile it, or some other sort of wrong)?
