It is said that every problem in computing can be solved by adding anohter layer of indirection. And so
we have many layers, which, when done right, help us to understand the system. (Read, layers are for us,
not the computer)
But implementing each layer comes with added cost, often unneccessary. Layers can and should be collapsed
in the implementation. Inlining, is a good example of this.
