<?php
/*
 * calc_bmi
 * The structure of this function is misleading and overcomplicated.
 * The function returns false or a value, so any program calling it must handle
 * either false or a value.
 * Further, the function is burdened with mistrust and has misleading default arguments.
 * The default arguments suggest that the function expects integers, but it actually handles strings and many other possible values.

Sessions, windows, panes

Session is a set of windows, plus a notion of which window is current.

Window is a single screen covered with panes. (Once might compare it to a ‘virtual desktop’ or a ‘space’.)
