Trouble with destroy

[Namespace]

Code:
----
import std.stdio;

struct A {
public:
	int[4] val;
	
	alias val this;
}

void main()
{
	A a;
	a.destroy();
}
----

/d824/f630.d(13): Error: template object.destroy matches more 
than one template declaration, 
/opt/compilers/dmd2/include/object.di(593):destroy(T)(ref T obj) 
if (is(T == struct)) and 
/opt/compilers/dmd2/include/object.di(604):destroy(T : U[n], U, 
ulong n)(ref T obj)

Nice. What should I do?
