A Question about explicit constructor

[meili100]

class Test{
private:
	int b;
public:
	explicit Test(int x=0):b(x){}
	explicit Test (const Test& ts):b(ts.b){}
};

int main(){

	Test ts=static_cast<Test>(1);//It's OK here
	Test ts2=static_cast<Test>(ts);// what's wrong here?
       
return 0;
}

What's wrong with the code? Why can't it be compiled?

Neither is OK for my compiler.

The aim of explicit keyword is to allow only constructs like that:

Test ts(1);
Test ts2(ts);

And to avoid situations like that

void foo(Test t);
...
foo(2); //OK without explicit

In other words, explicit makes the compiler stricter, and you should not use it to devise workarounds with funny casts.
