If youve read PPI::Token::Whitespace, you should understand by now
the concept of documents floating in a sea of PPI::Token::Whitespace.
Well it doesnt after the __END__ tag.
Once you __END__, its all over. Anything after that tag isnt even fit
to be called whitespace. It just simply doesnt exist as far as perl
(the interpreter) is concerned.
Thats not to say there isnt useful content. Most often people use
the __END__ tag to hide POD content, so that perl never has to see it,
and presumably providing some small speed up.
Thats fine. PPI likes POD. Any POD after the __END__ tag is parsed
into valid PPI::Token::Pod tags as normal. <B>ThisB> class, on the
other hand, is for whats after __END__ when it isnt POD.
Basically, the completely worthless bits of the file :)
