Can anyone point me to some GitHub code with a good use of spec?

Also, should I use a newer version of spec than the one that comes with 1.9.0?

@boccato If you're just getting started with spec, you might as well stick with 1.9 and the included version.

That is exactly my case, @seancorfield.

There are also some changes in the latest spec version that sort of assume some corresponding changes in 1.10 (and I think some of the REPL tools will need some changes to catch up as well).
