Hi all,
I am writing to propose using C++11 uniform initializer syntax in member
initializer lists. The following:
class A {
public:
    A(B&& b, float i, int j)
    : m_b(WTFMove(b))
    , m_i(i)
    , m_j(j)
    {
    }
...
};
Would become:
class A {
public:
    A(B&& b, float i, int j)
    : m_b { WTFMove(b) }
    , m_i { i }
    , m_j { j }
    {
    }
...
};
Using uniform initializer syntax in member initializer lists would make
the syntax we use for member initializer lists consistent with the syntax
we use for non-static data member initializers. It would also cause a
compile time error if member initialization required a narrowing conversion
(e.g. implicit float to int conversion). Another benefit of using this
syntax is that it allows initialization of a struct using aggregate
initialization.
