More Javascript WATs:

	[]+1	// "1" (a string, not a number)
	[]-1	// -1 (a number, not a string... WAT?)

	{}+1	// 1 (a number, not a string... huh?!)

	[]+"a"	// "a" (weird, but OK)
	{}+"a"	// NaN (WAT?)

Even worse:

	"a"+[]	// "a" (weird, but OK, consistent with []+"a")
	"a"+{}	// "a[object Object]" (WAT? inconsistent with {}+"a")
