It is related.  If I follow your suggestion to move these 
implementations to `core.internal` and continue with the 
objective of converting all runtime hooks to templates, the vast 
majority of `rt` will end up being moved to `core.internal`.  Is 
that what you're suggesting?

`rt` is the language implementation.  `core.internal` contains 
the utilities used internally by druntime and "privately" 
imported by Phobos.  Following that established convention, I 
made the right decision.

I'm sorry it broke digger, but digger is not how we typically 
build DMD, druntime, and Phobos.
