So the puzzle is to write a hello world program in your language of choice, where the program's source file as a string has to be a palindrome.
To be clear, the output has to be exactly "Hello, World".
Edit:
Well, with comments it seems trivial (not that I thought of it myself of course [sigh].. hat tip to cobbal).
So new rule: no comments.
Edit:
I feel kind of bad editing someone else's question to say this, but it will eliminate a lot of non-palindromes that keep popping up, and I'm tired of seeing the same simple mistake over and over.
The following is NOT a palindrome:
()()
The following IS a palindrome:
())(
Brackets, parenthesis, and anything else that must match are a major barrier to palindrome-ing, yes, but that doesn't mean you can ignore them and post non-palindrome answers.
