const_type! Good point, I hadn't thought of it. I'm thinking it may be a 
case of under-documentation. I believe I was originally told that 
const_type is primarily an implementation detail, whether I'm 
remembering incorrectly or that has changed, it might be a good idea to 
mention const_type and its' purpose in the documentation, along with (at 
least) a one or two line example for the sake of making things 
mind-numbingly clear. Hopefully, the (seemingly) oft-raised question can 
then finally be put out to pasture.
