--- Comment #31 from Steven Schveighoffer <[email protected]> --- I expect at some point for concatenation to be a fully lowered template function, and at that point, we have all the tools to do this. You can leave it open if you want, I was just looking through issues I had reported, and this one just struck me as being very stale, not just in time but in light of all the developments that have happened in D since 2007. --
