/**
 * This is from community accepted conventions and feel free to judge upon them.

 * Upon Method Invocation chaining, one can prefer the 'fooIndent' method over 'fooNotIndent'
 * (as well as barIndent over barNotIndent),
 * Not only it improves readibility upon reading (by gradually grasping the functionality) but also it does not consume
 * the whole screen (thus not making you scroll).
 *
 * The use of '.' upon invocation is debatable.
 * Some argue that the leading '.' should be removed [2]
