How are const and final different from one another in D?  Is 
the only difference that final variables may be initialized 
in the constructor, and const variables can only be 
initialized by declaration?  Or is final only involved in 
preventing class inheritance?

final doesn't apply to variables. Const applies to variables and means their
initializers must evaluate to compile-time constants. See

yup. See the first section of http://www.digitalmars.com/d/function.html. It
seems legal to declare an entire class as final but I'm not sure it does
anything.
