关于nodejs vm.runInNewContext()会出现内存泄露的一点说明

	var fs = require('fs');
	var vm = require('vm');
	var exp = require('express');

	var app = exp();
	var script = new vm.Script(fs.readFileSync("t2.js", 'utf8'));
	var context = { module: {} };

	var fn = script.runInNewContext(context);

插入排序的尾递归写法

	@scala.annotation.tailrec
	def _insertSort[T](x1: List[T], x2: List[T])(p: (T, T) => Boolean): List[T] = x2 match {
	case Nil => x1
	case x2_head :: x2_tail =>
	val (x1_left, x1_right) = x1.partition( x => p(x, x2_head) )
	val x1_new = (x1_left ::: (x2_head :: x1_right))
	_insertSort(x1_new, x2_tail)(p)
	}

	def insertSort[T](xs: List[T])(p: (T, T) => Boolean) = xs match{

关于方法执行顺序的问题

	class Op(var x : Int) {
	def +++(op: Op) = { println(this.x+ " +++ "+op.x); this.x += op.x; this;}
	def *(op: Op) = { println(this.x+ " * " + op.x); this.x *= op.x ; this;}
	}

	val op1 = new Op(1)
	val op2 = new Op(2)
	val op3 = new Op(3)
	val op4 = new Op(4)
	op1 +++ op2 +++ op3 * op4 //be equivalent to op1 +++ op2 +++ (op3 * op4)

一个比较难懂的隐式转换过程

	object TernaryOp {

	println("is ... ")
	if (bte.branch(t)) bte.then(t) else bte.elze(t)
	}
	}
	class Branch[T](branch: T => Boolean) {
	println("branch");
