#112 is VERY bad. If you ever have to validate an email address, you might want to speed a few minutes and find a regex that does it right. It is a complex problem that does deserve some time. Do NOT roll your own solution just because you [think you] can.
In this case, enforcing the dot in the domain part is a bad idea not only because it violates the standard (that would be RFC 822) because there are legitimate use cases. for example:
* special domains (like "localhost" for example (there *are* others). Administrative mail on linux gets delivered to root@localhost by default.)
* intranet-only applications where clients have a dns search domain
I know of one company that has two dozen (no kidding) different functions their flagship product that are supposed to validate email addresses. Most of them are non-trivial and definitely took some time to implement. Not one of them is correct.

It would be nice if you left your e-mail address. Sometimes I want to send a private message, or just thank for the great comment. Having your e-mail really helps.
I will never ever spam you.

* use <pre>...</pre> to insert a plain code snippet.
* use <pre lang="lang">...</pre> to insert a syntax highlighted code snippet.
For example, <pre lang="python">...</pre> will insert Python highlighted code.
* use <code>...</code> to highlight a variable or a single shell command.
* use <a href="url" nospam>title</a> to insert links.
<a href="url" nospam>title</a>
* use other HTML tags, such as, <b>, <i>, <blockquote>, <sup>, <sub> for text formatting.

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
