Generally I prefer to avoid adding lots of code, and gigantic regexps count as lots and lots of code!

Ruby has a built-in regexp for email validation, namely `URI::MailTo::EMAIL_REGEXP` which is recommended for most situations. That way, someone else can be in charge of maintaining and debugging the regexp.


I'm not sure if that will work with the semi-colon delineated approach, but it's worth seeing if it can be made to work since I think it's much simpler, easier to read, and less to maintain.
