Oops, i guess the documentation is currently wrong in that
order! is not optional.  But a noop block passed to order!
should work for now.

I will make it optional for the next release, and probably
allow the proc as an arg to thread! to simplify the API.

Thanks for the report and sorry for the breakage!
