How it works

Since the code block (lambda, anonymous function)

{""''!$%&amp;()*+,-./:;&lt;=&gt;?@[\]^_`|~#
}


does not contain any syntax errors, it will be pushed on the stack and printed verbatim if left on it. The linefeed is required to end the comment that # started.

Finally, ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 is an undefined token; it does nothing.
