What is the performance difference, if any, between if(!foo) and if(foo == false) in Java?

I was unable to find an answer in the JLS, and searching brought up a lot of results about = vs. == typos and ==/equals() behavior. (In this ca...

Similar language features to compare with Perl and Ruby __END__
Background Perl and Ruby have the __END__ and __DATA__ tokens that allow embedding of arbitrary data directly inside a source code file.

Question: What other programming languages sup...
