Sure. I was only trying to clarify Laura's description of Something
and Nothing (as I saw it), because I like the description.

Although I think the new bool type was completely unnecessary, it
won't cause great problems for me, and I don't think I'll have any
problems explaining how it works to newbies (though I may have some
problems explaining why it exists).
