 ### Resolution Algorithm for Relative Constants
 
 At any given place in the code, let's define *cref* to be the first element of

-into the details, the resolution algorithm for relative constant references goes
-like this:

+2. If not found, then the algorithm walks up the ancestor chain of the cref.
 
 3. If not found, `const_missing` is invoked on the cref.
