```cpp
template<class T>
class Tuple
{
public:
Tuple(const T* pTup) : m_tup[0](pTup[0]), m_tup[1](pTup[1]), m_tup[2](pTup[2]) {}
protected:
T m_tup[3];
};
```
I use clang.exe to compile the above code it will tell me ```error: expected '(' or '{'```
But it will have no error in cl.exe.
Should we need to support this?
I am not very familiar with clang parser.
My thought about this is I can change some logic in clang parser and add one AST Node like ```MSArrayInitListExpr``` to fix this error.
At the same time, I found the following code,
```cpp
template<class T>
class Tuple
{
public:
Tuple(const T* pTup) : m_tup{pTup[0], pTup[1], pTup[2]} {}
protected:
T m_tup[3];
};
```
Its ast is
```bash
`-ClassTemplateDecl 0x20423924f00 <test.cpp:1:1, line:9:1> line:2:7 Tuple

```
Maybe I can simplify this problem by giving ```<<<NULL>>>```.
I would be very grateful if someone knowledgeable in this area could offer me some advice.
