class Google::Cloud::Env::LazyDict

@private

This expands on {LazyValue} by providing a lazy key-value dictionary. Each key uses a separate LazyValue; hence multiple keys can be in the process of computation concurrently and independently.

We keep this private for now so we can move it in the future if we need it to be available to other libraries. Currently it should not be used outside of Google::Cloud::Env.
