A bit broken, but getting there.

Start being much stricter about requiring StaticTuples everywhere.
I may go back and loosen this restriction, but getting the code base
StaticTuple pure is probably a good idea. The main reason to be 'looser'
is so that things don't fail 'in the wild' just because someone
calls an api with a tuple rather than a StaticTuple.
However, I'd like the internals to be 'pure' if possible.
We'll see.
