The issue here is if both type and types are specified, which one  
wins? Since types can be both single or multiple types, I think  
there's less opportunity for error if there is only one element, and  
types does it. And it is evocative of the notion that even though you  
specified a type on your field/property (or not, for unadorned  
collection/map types), there are more constraints on the actual types  
that you can put into it.

I'm still open to discussion, so if we can come up with an elegant  
way to solve the "both specified" issue, let's continue.

Meantime, I'll check in the change from boundTypes to boundType to  
keep things moving.
