Everyone here who is suggesting that function bodies should be
confined to ANY length is an idiot. The length of a functions code
block is inconsequential. Don't worry if it too small or too big. It's
not the size that matters, it's the motion of the sources ocean!
A good function can be one line, or a hundred lines. Always use
comments to clarify code and NEVER EVER create more functions only for
the sake of short function bodies, WHY, because all you do is move
confusion OUT OF the function body and INTO the module/class body.
