 ## Conversion Costs ##
 Each possible resolution of an expression has a _cost_ tuple consisting of 
-the following components:
-1. _unsafe_ conversion cost: summed degree of unsafe conversions; unlike CFA03, this is not a simple count of conversions (for symmetry with the safe conversions)
-2. _polymorphic unifications_: count of parameters and return values bound to some polymorphic type for boxing
-3. _type variables_: number of polymorphic type variables bound
-4. negated _type specializations_: Each type assertion specializes the polymorphism, thus decreasing the cost; nested polymorphic types (e.g. `T*`) are also counted as specializations
-5. _safe_ conversions: summed degree of safe conversions
-6. _qualifier_ conversions: summed degree of qualifier and reference conversions
+the following components: _unsafe_ conversion cost, _polymorphic_ 
+specialization cost, _safe_ conversion cost, a count of _explicit_ 
+conversions, and _qualifier_ conversion cost. 
 These components are lexically-ordered and can be summed element-wise; 
 summation starts at `(0, 0, 0, 0, 0)`.
