Another fun feature of ruby is the __END__ keyword. If that keyword appears alone on a line, ruby will stop parsing the file at that line. In the same file you can use the magic DATA variable to read the rest of the file.
This program will output Hello\n when executed.
This allows to easily create self-unpacking scripts for example, or to join data with code.
This feature is present in Perl too.

Very similar article that seems to be easier to understand and read than this one.

What you say is very subjective..
