Regexp-based e-Mail Address validation (according to RFC822)

[Andrey_Dmitriev]

One of the best regexp which I have seen:

How funny... And seems to be working...

There really should be a law against doing something like that in LV.

Wow..   That's quite the algorithm.  I had a quick look at the link that you provided..

Someone had a bit of time on their hands..

How would this be useful?  Reduce SPAM?

Other than the "wow" effect, is it useful?

I don't know - it's kind of mesmerizing if you look at it for a while.

NO NO don't listen to the sirens! They'll tempt you in with their gracful curves and subtle umlats but don't be fooled! The next thing you know you will be thinking syntax, and dogs and cats will be living together...

I have that nagging feeling that it could be done with about 3 fewer characters. 😮

For bonus points colour code by character (ala paint by numbers), and use a monospace font.

edit:It also compresses down quite nicely.

That's a neat way to obfuscate code. I guess there are tools available that can blow any given regExpr. But on the other side, these tools will also allow (maybe more intentional) simplify the regExpr down to a human readable format again.
