Nowadays you read more and more about DSL and Fluent APIs / Fluent Interface, which I was to reminded when I bumped into jQuery today (by doing some JS related work).
In jQuery you can do things like:
$('<p></p>')
.html("Blah, blah, blah")
.addClass("foobar")
.appendTo("body");
This code simply adds a new paragraph to the current page, nothing special with that, but it is done with a very sexy and well readable syntax. It is truly worth to evaluate jQuery in detail!
