This step when taken alone smells like it is going backwards in the
readability department by going from a set meaningful names to
another set of more cryptic names, but together with 3/3 where the
designated initializers clarify what these cryptic args with short
names correspond to, the end result gives us a pleasant read.

Thanks.
