I have this struct:

I would name it dup instead of copy for consistency with D. A copy

Thanks, I'd already realised I ought to rename it .dup.
Also, I only actually need to create it from the keys since I'm using
the tags AA as a set so every value is the same. I did try tags.dup but
got this:
src/deb.d(25,24): Error: cannot implicitly convert expression
dup(this.tags) of type const(void[0])[string] to void[0][string]
Right, because it's inside a const member function, the tags member is
const.
Right now, it looks like dup does not work even for value types (e.g.
const int[int] -> int[int]) let alone types with indirection (it should
also work for string keys). If there's not an issue already, someone
should file it.
