Why is it that this code (correctly, in my opinion) fails to compile:

Code:

struct Foo {
	int value;
};

struct Bar {
	int value;
};

Foo foo;
Bar bar = foo;

Yet this code compiles just fine.

Code:

template<typename T> struct Value {
	T value;
};

typedef Value<int> Foo;
typedef Value<int> Bar;

Foo foo;
Bar bar = foo;

Is there anyway to get struct typing behaviour with templates? Why does C++ behave this way? If it helps, I'm using gcc 3.2.3
Thanks!
