The following program cause the compiler to dump core. I would
actually like to see the restriction on cast operators (namely, that
they can only be defined as member functions) be dropped, at least in
GNU C++. Allowing the definition of cast operators outside of classes
would make it easier to integrate different class libraries.

================================================================
struct ipoint2 {int x,y;};
struct vec2 {float v[2]; vec2(float x,float y) {v[0]=x; v[1]=y;}};

operator vec2(ipoint2 &p) { return vec2(p.x,p.y); }

main() {
	ipoint2 p;
}
