+### Retry
+
+#### 详细描述
+retry 对第二个参数作为函数的情况，重试N次，如果第二个参数返回值是 true，则重试，否则就结束，如果遇到错误，停止重试
+
+Example:
+```
+count = 0
+
+	retry(100, () => {
+	   defer recover()
+
+	   count++
+	   if count > 3 {
+	       die(111)
+	   }
+	   return true
+	})
+
+assert count == 4, f`${count}`
+
+count = 0
+
+	retry(100, () => {
+	   defer recover()
+
+	   count++
+	   if count > 3 {
+	       return false
+	   }
+	   return true
+	})
+
+assert count == 4, f`${count}`
+
+count = 0
+
+	retry(100, () => {
+	   count++
+	})
+
+assert count == 1, f`${count}`
+
+count = 0
+
+	retry(100, () => {
+	   count++
+	   return true
+	})
+
+assert count == 100, f`${count}`
+```
+
+
+#### 定义
