I think his point was that the definition of the class of regular
expressions is recursive, for example "E+F is a regular expression if
E and F are both regular expressions", "E* is a regular expression if
E is a regular expression", etc. The definition of Lua patterns is not
done in this way, it is done as: pattern -> pattern item -> character
class.
