I concur. This function is trivial, and it's doing something that arguably should not be encouraged. `to!string` does the safe thing by allocating a new string, which is what we want. If you really want to do something unsafe like this, you should know what you're doing, and it's so trivial to just do it on your own, that this function doesn't buy you much, and it comes with the distinct downside of encouraging people to do the unsafe thing rather than the safe thing - potentially without properly understanding the repercussions of doing so.

So, I vote for closing this pull request.
