C++ std::list paramerter with default values

Question

I want to have a method that takes a list as a parameter but this list should have default values, here is an invalid example for what I need:

void myFunc(std::list<CString> const & myList = std::list<CString>({"Val1", "Val2", "Val3"}));

When I try to use it I get

Error C2143: syntax error: missing ')' before '{'

Micrsoft Visual Studio 2010 does not support std::initializer_list. When you do

std::list<CString>({"Val1", "Val2", "Val3"})

You attempt to initialize the std::list using it's std::initializer_list constructor. Since MSVS 2010 doesn't support that you can call it.

One thing you can do is write a function that creates and initializes a list like

std::list<CString> default_list()
{
    std::list<CString> temp;
    temp.push_back("Val1");
    temp.push_back("Val2");
    temp.push_back("Val3");
    return temp;
}

And then you can use that like

void myFunc(std::list<CString> const & myList = default_list());
