That is of course possible, but I'm not convinced it is desirable.
1. I like to keep the interface minimal.
2. A few calls to C++ standard library functions may be easier to read
than a single call to a custom function.

I have never had any use for that particular functionality myself.
But it is in TR1.


Thanks for the review!
