GC pressure, since ValueLayout instances are immutable. While it won't 
matter here specifically since it'll be GC'd once and done, I'm worried 
about cases where a ValueLayout(or any other layout type) needs to be 
put together on-the-fly very frequently.

If you had the ability to define a group of Constable objects(which can 
then be made constants), you could then at the very least cut down on 
the amount of garbage.
