As a follow-up to this thread, I discussed the matter on #perl6 with
Larry today (before the thread on mutable arguments), and I learned
that one of my main concerns, of inconsistency between different
collection types, is not valid.

1. Not just Array, but also Seq can typically bind to both @ and $.
2. Not just Hash, but also [Mapping,Set,Bag,Pair,etc] can bind to
both % and $.
So its not just Array and Hash with the extra sigils, while
everything else has only the $.
I now recommended that the Synopsis be updated to explicitly clarify
such as these details, to make things less ambiguous for future
readers, and they don't make the same mis-assumptions that I did
about the limited scope of @ and % use.
That is, the Synopsis should explicitly state which are all the
built-in types that could typically bind to each of the sigils (and
everything can bind to $).
Larry thought that perhaps S02 would be the place for it.
In conclusion, I retract my previous suggestion of just using $ where
we used to use @ and %.
