I'm instantiating a couple of template structs that conflict with 
each other. I'd like them to be unique types, automatically. So I 
tried this:

template Foo (string unique_id = __FILE__~__LINE__.to!string)
{...}

but it didn't work. When I use this for templated functions, I 
get the file and line number where the function is instantiated. 
But in this case, I got the file and line number where the 
template was defined.

Is there anything I can do to make sure each instantiated type is 
unique?

I don't think you want to set a default value. If you pass 
"__FILE__~__LINE__.to!string" during instantiation, it works every time:

template Foo(string uniqueId)
{
	alias Foo = uniqueId;
}

void main()
{
	Foo!(__FILE__~__LINE__.to!string).writeln;
}

Of course Foo2 could be an enum :)
