	\nn\t3::Arrays('1,,2,3')->trimExplode( false ); // [1,'',2,3]
	\nn\t3::Arrays('1|2|3')->trimExplode('|'); // [1,2,3]
	\nn\t3::Arrays('1|2||3')->trimExplode('|', false); // [1,2,'',3]
	\nn\t3::Arrays('1|2,3')->trimExplode(['|', ',']); // [1,2,3]
	\nn\t3::Arrays(['1','','2','3'])->trimExplode(); // [1,2,3]
