for entirely new specs or when we're doing a lot of work on a spec file, its generally encouraged to use rspec 3 syntax and use let blocks in favor of ivars, and to convert the whole spec file.  for a patch of this size, however, we'd rather accept the patch and allow it to be consistent with the existing syntax in the file.
