Why can't member variable be initialized?

[Marc G]

At the time of creating C (and their structs), there was no such thing as construction. In C++, they probably didn't even think about it. They considered it for C++0x, but finally dropped it.

What was dropped in C++0x? Any references?
The following code is perfectly valid in C++0x (draft version ISO/IEC JTC1 SC22 WG21 N3092)

struct A
{
    int i = 0;
};
