> {{ObjectUtils.firstNonNull}} takes values, and returns the first non null. This is often used when multiple options have to be tried one after another.
> When each option is expensive to compute, you don't want to calculate them all beforehand, but only evaluate them when needed. For this I propose {{firstNonNullLazy}}, which takes a Supplier and only evaluates the value if it needs to be checked.
