PRETTY K CODE

PALINDROMES

	These are k expressions that are palindromes (save for parens and brac-
	es) and evaluate to 0 despite having no numbers actually present in the
	expression.

	"":_#_:""
	"."-"."
	""~""~""

	People in the aplfarm k room also provided some more palindromes:

	Razetime shortened one of the above to be `~`~`
	He also made the shortest possible palindrome: `<`
	AND he came up with my favorite so far: boobs ((.)(.))-((.)(.))

EMOTICONS

	These emoticons are valid k expressions or functions.

	(^_^) is an expression which evaluates to 0 no matter what value is pas-
	sed into it. Try

		(^_^)'!100

	(;w;) is a little trickier because we need to define w, which makes it
	not as pretty. A full working expression would be {[w];w;}'!10, which
	simply returns 10 ::s.

	(*_*) returns any integer passed into it.

	{x\\\\x} simply hangs ngn/k. Weird!
	{x////x} doesn't though.

	(d:) (like a reverse ":p") just returns whatever value is passed into it
	(and technically makes a new local variable...before it immediately goes
	out of scope again). Try

		(d:)'!100

	{'.'} returns a `.` no matter what is passed in.
