It would be nice to have the following code legal in C++.


template <class T> void ImpFunc();


template <class ... TT>

void Func(int sw)

 {

  switch( sw )

    {

     *{* case TT::Val : ImpFunc<typename TT::Type>(); break; *}...*

    }

 }

The red line should be template parameter pack expanded. In other words, we
need the statement pack expansion. The statement pattern is enclosed in
square brackets and terminated with ellipse.

You proposed this just days ago. The next step would be to write a draft following the general format of the papers found at http://open-std.org/jtc1/sc22/wg21/docs/papers/2014/ .
