A more conservative approach would be to put them in 
`core.internal`.  `core.internal.traits` is already there.  My 
understanding is that anything in `core.internal` is not intended 
for public consumption, so we could start there without 
committing to a public interface that we'd have to maintain.  It 
can always be exposed publicly later when the future becomes more 
clear.
