Use Delegate.CreateDelegate() (example, example, example) to create a delegate and cache it as part of e.g., MemberDispatcher, if not TypeMemberInfoCollection and MemberInfoCollection<>. This should dramatically improve performance.

Ideally, this should be applied to Topic classes and model classes. For Topic classes, this needs to account for Get{Attribute}() methods as well as [AttributeSetter] and [ReferenceSetter] properties. For model classes, this needs to account for properties and constructors. These may be able to be handled by a single class, though they may be better served by specialized classes.
