Comment by Yahya Abdal-Aziz (published 2010-05-18) Mostly excellent; however, I see these potential problems for new regex users: 1. Is space a literal character i.e. matching "[ ]" or some special character e.g. "\x" ? 2. What do you mean by "a word boundary"? 3. If counts "apply to previous element", what defines, bounds or marks an element? 4. You write: "Add a ? after any count to turn it sparse". Would that be, e.g., "{4,8?}" or "{4,8}?" ?
