I think you meant `idup`? `dup` will make it mutable.
`dup` actually works. I tested the code before posting. It
should be that `dup` is a template function which gets inferred
as strongly `pure`, so the result is known to the compiler to
be unique.
Oh, that’s awesome I didn’t know pure stuff can do that.

So perhaps `idup` is no longer needed.
It’s more explicit so I think still generally preferable.
