The value of a successor-taint is in summarizing the history
of the taint objects derived from a common parent. For
example, consider a casereader that represents the active
- file. A statistical procedure can clone this casereader any
+ dataset. A statistical procedure can clone this casereader any
number of times and pass it to analysis functions, which may
themselves in turn clone it themselves, pass it to sort or
merge functions, etc. Conventionally, all of these functions
