groovy list transpose和each的特殊用法

源码：

class TestTranspose {
	static main(args){
		def list = [[1,4],[2,5],[3,6]].transpose()
		println list//[[1,2,3],[4,5,6]] 行和列置换
		[[1,3,4,[6,7,8,9,10]].each {k,v,j,h,l->
		println "k:${k},v:${v},j:${j},h:${h},l:${l}"
/*			k:1,v:2,j:3,h:4,l:5
			k:6,v:7,j:8,h:9,l:10*/
		 		}
		[[1,2],7]].each {k,v->
			println "k:${k},v:${v}"
/*k:1,v:2
k:6,v:7
*/		}

/*		[1,5].each {k,l->//报错
			println "k:${k},l:${l}"
		}*/
	}
}
