---------------------------------------------------------------

Its because of the loss of whats going on in PayloadTermQuery - we also lose 
some custom info from PayloadNearQuery - on first blush it seems best just to 
leave the exp in the scorer for Span queries - its still gone from Scorer so I 
don't see it as much of a problem myself - havn't thought on it much yet though.

I guess we could pull all that custom info up to the weight through the 
span/payload stuff - but then each has to duplicate a bunch of the info from 
the SpanWeight - it seems nicer just to leave things as they are, let the 
Scorer do it, and cast. What do you think?

> This is the only remaining deprecation in core, but is not so easy to handle, 
> because lot's of code in core still uses the explain() method in Scorer. So 
> e.g. in PhraseQuery, the explain method has to be moved from Scorer to the 
> Weight.
