Email address: RFC 2822

This regular expression implements the official RFC 2822 standard for email addresses.  Using this regular expression in actual applications is NOT recommended.  It is shown to illustrate that with regular expressions there's always a trade-off between what's exact and what's practical.

Words: Any word NOT matching a particular regex
