The initial kernel (Rx) is now much tighter, eliminating wasted space
and tail calls for better performance.
I rewrote several combinators in the `s:` namespace. This eliminated
several variables and makes things cleaner and a little faster. I also
added `s:case` and `s:with-format`.
There are new `@` and `!` prefixes for fetching and storing to
variables. These should lead to some nice reductions in visual noise
and allow for easier maintenance of code.
The iOS version is getting a nice update as well, adding in support
for an interactive listener.
Atua has some updates. It now supports files up to 6MiB in size, and
the WWW variant now supports detecting and reporting Content-type
headers for better compability with Chrome.
