I just saw that comments at the end of the article also mention variable name disambiguiation (eg "${foo}_bar"), didn't think of that one.

So if we count the regex uses that's 7, and if we don't it's only 5 (seems there's no reason to count the quoting uses, since pretty much anything can be used there).
