The chain of functions still passively passes-through the functional arguments,
and do nothing with them at the end.

Lets stop that practice in the code.

Factoring-out the function passing from the functions - allows to just apply the
previously passed function exteriorly.

Which siplifies the implementation, code reads and understands better, functions
specialize on what they do, so GHC can optimize them better.

This actively shows the refactoring practice.
