I think the @Once{} syntax looks much more appealing than ${}, as Gordon
states it looks a lot more consistent with other directives and it also
expresses its intent much more clearly. I like this proposal as an addition
to the framework. I would expect @Once to set the value one time during
instantiation of the object with the directive, waiting for first non-null
just doesn't sound like a good thing.
