What happened was:

1. You told me it could cause termination.
2. I made a test case, and observed that it didn't cause termination on
construction, and that due to the implementation, no copy was made, so it
didn't test the copying (which may cause termination).
3. You said it was irrelevant that no termination was observed.
4. I said that I hadn't claimed the test proved there would be no
termination, since on that platform, the copying wasn't tested.

As you can see, I agreed with you from the beginning. It just seems that you
thought I claimed that since it didn't terminate, it wouldn't do that on any
platform. I didn't mean that, and it seems this misunderstanding was the
cause of this long discussion.

I don't disagree with that. I merely made the point that my implementation
also fulfilled the request, which it seems you now agree to, as well.

I also think returning the type as type_info is better.
