Take a look at this:

It's like XML only human readable and writeable. Much less verbose.

BTW, the author is an Erlang expert.

Well, I don't know about switching to ML9,
which primarily looks like a LaTeX replacement.

But the Erlang author has some slides about robust systems on
  http://www.sics.se/~joe/talks/systems.pdf

One item in there is:
in order to be robust, processes _share nothing_,
message passing is the only way to exchange data,
and data must be copied.
"Good Stuff: Processes, Copying, Message Passing".

I guess the real-world situation of a V3 IOC,
with ideas to avoid copying arrays,
or the recent exception discussion where
some try to avoid copying or even generating the error message,
falls into his summary of
"Bad Shit: Threads, Sharing, Mutexes, ..."

Fun reading for a Friday afternoon.
