silently accept &parentclassName.func can be bug-prone

[davidl]

import std.stdio;
class t
{
	void func(){writefln("t");}
	void delegate() getdelegate(){return &func; }
}

class v:t
{
	void func(){writefln("v");}
}

class r:v
{
	void func(){writefln("r");}
	void delegate() getdelegate(){return &t.func; }
// someone write this may expect the compiler to return the delegate of  
func in class t
}

void main()
{
	r p= new r;
	p.getdelegate()();
}

currently it prints "r"
