My comment that it is a C++11 thing is probably wrong. I did not check 
what level of standard allows QPair without specialization. This issue 
was the reason why std::pair has a make_pair(), I think.

I have not tried it, but transforming a char to string is probably as 
easy as {c} in the right context, instead of the horrible string(1,c).
