add_facet got added to address a short-coming of the older dinkumware library. It would not really be needed except for this.

As to why I did it they way I did - I don't remember. I would guess that I didn't want any more copying than necessary and this implementation worked fine for me.

Sounds reasonable. My guess is that the extra copy will typically be optimized away, but I haven't verified this.

If you want to make version similar to that which you propose and put it an agreed upon public place, I can eventually included your more generally usual formulation

Okay.
