Preparing plugins for 1.0.0: Looking for documentation reviewers

Has someone tested the example code for the Leader plugin? I’m getting compilation errors.

Edit: Also, it was a bit confusing to figure out what that “magic number” in “LEAD(0)” was supposed to mean.
It would be nice if the example code actually referred to the examples used to describe the use case of the plugin (I know, it’s not easy to implement since it’s using the Unicode plugin, which doesn’t work without further configuration).
