digitalmars.D - Where in docs?

This works:

       printf("%d\n", x.size);
    }
}


void main(char[][] args)
{
    foo!(int) y;
    y.getsize();
}

I would just like to know where in the documentation this kind of 
generic programming is listed or if it is listed at all.

Thanks,

Paul

I think you've discovered another undocumented template trick.

It should be mentioned on http://www.digitalmars.com/d/template.html, 
but the closest thing seems to be:

<quote>
If a template declares exactly one member, and that member is a class 
with the same name as the template:

	template Bar(T)
	{
	    class Bar
	    {
		T member;
	    }
	}
	

then the semantic equivalent, called a ClassTemplateDeclaration can be 
written as:

	class Bar(T)
	{
	    T member;
	}
</quote>

Where's the trick? struct templates? I think that's been mentioned before...

It may have been mentioned before. My point was that I couldn't find it 
in the docs. I think it was possible to do the similar class syntax 
before it was documented. If a similar thing can be done with structs 
now, it should be documented.

I suggest writing the amendment and sending it to the bugs forum.

Parhaps there should be a d documentation amendments newsgroup.  I mean, 
we don't get many now but if there was one I'm sure there would be many 
more if there was a place for it.  I'm sure that would be a big help to 
Walter.

I'll start a new thread on that matter.
