> A few things i noticed, while trying to work on e.g. integration of this with
> solr and just playing around:
> * No way for a custom Bindings to currently bind the score, as the necessary
> stuff is package private. This adds a simple protected method to Bindings to
> enable this.
> * Expression.getValueSource() cannot in general be used easily by other
> things (e.g. interoperate with function queries and so on), because it
> expects you pass it this "custom cache". This is an impl detail, its easy to
> remove this restriction and still compute subs only once.
> * if you try to bind the score and don't have the scorer setup, you should
> get a clear exception: not NPE.
> * Each binding is looked up per-segment, which is bad. we should minimize the
> lookups to only in the CTOR.
> * This makes validation considerably simpler and less error-prone, so easy
> that I don't think we need it in the base class either, I moved this to just
> a simple helper method on SimpleBindings. It also found a bug in the equals()
> test.
