I've been thinking about the name. I realize that it's not a true monad
in the Haskell sense, even though the implementation *was* inspired by
deadalnix's mentioning of the Maybe monad, so we really should call it
something else.  "failsafe" sounds a bit too generic. What about
"safeDeref" or just "deref"?

OTOH, I wonder how easy it would be to refine the current implementation
to become a true monad?
