+利用无限重复块避免深层递归
+-------------------------------------------------------------------------------
+在 [重复块](#重复块) 一章中, 有说到重复块无限重复的情况,
+可以利用它来替换掉一些用递归解决可能远超递归层数限制的问题
+
+例如如果想给一千以内整数附加上一个 pi 绑定量:
+
+```
+const Each = (match @ {
+    [1000] {}
+    N {
+        take*N.pi = N*3.1415926535897932;
+        take Each[(*N+1)];
+    }
+});
+Each! 0;
+print 8.pi;
+```
+编译上述代码, 产生递归超限, 我们可以利用无限重复块将其改为:
+```
+{
+    take N = 0;
+    inline 0@{
+        match N { [1000] { Builtin.StopRepeat!; } N {
+            take*N.pi = N*3.1415926535897932;
+            take*N = N+1;
+        } }
+    }
+}
+print 8.pi;
+```
+编译为
+```
+print 25.132741228718345
+```
