My reply was about the comment "No need to check for any overflows." - 
obviously if you do C++ programming you need to know how to check for 
integer overflow (and we all know how to use '+' with std::string, but 
we may also need to calculate e.g. a length of a std::vector to resize, 
and check for overflow in the process)

The fragment you posted obviously works well with no need for unsigned 
wrapping (I didn't say you can't do without, I said it's more efficient 
and less verbose if you have it), but it also has different requirements 
than the example I posted: two strings only, with the precondition that 
the 'this' string is less than max_size() long.

Just to stick with this example (although my point was about integer 
overflow rather than string concatenation), you see that if you lift 
these preconditions and need to concat more than 2 strings (as it was in 
the example) then either you precalculate the total length of the final 
string with a series of additions (and you see that the example is more 
efficient, more clear and less verbose than a series of if/else) or you 
do string+string+string and you end up with multiple allocations and 
copies (and yes, as often as this is totally irrelevant, sometimes this 
does matter).

This is to say that if you want to handle integer overflow efficiently, 
then unsigned wrapping /is/ useful, it is not a "major design mistake" - 
which is what triggered all this (for me at least).
