Hi,

I'm curious about the decision taken to not allow string_ref to modify the
data it represents.
I'm modifying our JSON parser to use it, and sometimes I need to normalise
a field to
uppercase or lowercase. Obviously I cannot now do this without making a
copy of the normalised field somewhere with either std::string or
boost::string_ref.

I notice Jeffrey Yaskin's proposal for a standard implementation (
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3442.html) has
also taken this design decision, which is disappointing.
