Apropos string_ref, I would like to see lexical_cast extended to
support a Range concept.

lexical_cast has optimizations for ranges with character types since 1.50: http://www.boost.org/doc/libs/1_55_0/doc/html/boost_lexical_cast/changes.html

It also has a

lexical_cast(const CharType*
                chars,
                std::size_t count)

function since 1.52. And I'm afraid that's all what can be done without breaking the initial interface and behavior of LexicalCast library.

Or were you talking about some other "range concept" support?
