Only my personal experience with git blame. The `.cast()` call itself
is boilerplate that arises from the difference in types between the
abstractions and the bindings; my opinion is that a user of git blame
is more likely to be interested in the rationale accompanying the
implementation rather than that of the type shuffle.
