Weirdest obfuscated "Hello World!" Task:

Create an obfuscated program that prints Hello World! (exactly like that). Your program may not have any strings in it.

Rules:


You can use any programming language you like.
Make it as obfuscated as possible
This is a popularity-contest, so the answer with the most upvotes wins.




Note:

This is not a duplicate of this question. That one was code-golf and it had different rules.
Python 2

I happened to be playing with this yesterday, so:

(lambda _, __, ___, ____, _____, ______, _______, ________: getattr(__import__(True.__class__.__name__[_] + [].__class__.__name__[__]), ().__class__.__eq__.__class__.__name__[:__] + ().__iter__().__class__.__name__[_____:________])(_, (lambda _, __, ___: _(_, __, ___))(lambda _, __, ___: chr(___ % __) + _(_, __, ___ // __) if ___ else (lambda: _).func_code.co_lnotab, _ &lt;&lt; ________, (((_____ &lt;&lt; ____) + _) &lt;&lt; ((___ &lt;&lt; _____) - ___)) + (((((___ &lt;&lt; __) - _) &lt;&lt; ___) + _) &lt;&lt; ((_____ &lt;&lt; ____) + (_ &lt;&lt; _))) + (((_______ &lt;&lt; __) - _) &lt;&lt; (((((_ &lt;&lt; ___) + _)) &lt;&lt; ___) + (_ &lt;&lt; _))) + (((_______ &lt;&lt; ___) + _) &lt;&lt; ((_ &lt;&lt; ______) + _)) + (((_______ &lt;&lt; ____) - _) &lt;&lt; ((_______ &lt;&lt; ___))) + (((_ &lt;&lt; ____) - _) &lt;&lt; ((((___ &lt;&lt; __) + _) &lt;&lt; __) - _)) - (_______ &lt;&lt; ((((___ &lt;&lt; __) - _) &lt;&lt; __) + _)) + (_______ &lt;&lt; (((((_ &lt;&lt; ___) + _)) &lt;&lt; __))) - ((((((_ &lt;&lt; ___) + _)) &lt;&lt; __) + _) &lt;&lt; ((((___ &lt;&lt; __) + _) &lt;&lt; _))) + (((_______ &lt;&lt; __) - _) &lt;&lt; (((((_ &lt;&lt; ___) + _)) &lt;&lt; _))) + (((___ &lt;&lt; ___) + _) &lt;&lt; ((_____ &lt;&lt; _))) + (_____ &lt;&lt; ______) + (_ &lt;&lt; ___))))(*(lambda _, __, ___: _(_, __, ___))((lambda _, __, ___: [__(___[(lambda: _).func_code.co_nlocals])] + _(_, __, ___[(lambda _: _).func_code.co_nlocals:]) if ___ else []), lambda _: _.func_code.co_argcount, (lambda _: _, lambda _, __: _, lambda _, __, ___: _, lambda _, __, ___, ____: _, lambda _, __, ___, ____, _____: _, lambda _, __, ___, ____, _____, ______: _, lambda _, __, ___, ____, _____, ______, _______: _, lambda _, __, ___, ____, _____, ______, _______, ________: _)))

Notes:


One line, single expression (i.e. no print statement).
No strings, no ints; only functions, attribute access, lists, tuples, basic math, one True, and one star-args.
Minimal builtin usage (__import__, getattr, and chr once each).
The payload can be changed easily. Here is the program I wrote to generate it.


Edit: I wrote a fairly substantial explanation of how this works on my blog.
