It properly encapsulates area initialization, like cleaning up scratch variables wanted only for the initialization, with no need to produce a needless nonlocal nevertheless nonreusable function. In addition, it works for variables that should be const but only soon after some initialization work.

This means we can location multiple assertion on a single line, or put a single assertion across several lines. We could produce a functionality with no line breaks. Due to the fact we almost never make hardcopy printouts of our software program, It's not at all needed to lessen the quantity of line breaks.
