Subject: [boost] [string_ref] string literal constructor

I noticed string_ref doesn't have a constructor for a string literal.
Wouldn't this save a call to strlen for a common case?
template< std::size_t N >
basic_string_ref( const charT( &str )[N] )
: basic_string_ref( str, N-1 )
static_assert(N >= 1, "not a string literal");
string_ref test( "test" );
I see that adding this directly doesn't work as the compiler is always
choosing to decay and pick the const char* overload.
Is there no way to make this work?
