Same as the primary operator+ with an rvalue lhs C-string.

operator+(

bsl::basic_string<CHAR_TYPE, CHAR_TRAITS, ALLOCATOR>
operator+(
basic_string<CHAR_TYPE, CHAR_TRAITS, ALLOCATOR> const& lhs,
CHAR_TYPE rhs);Return the concatenation of strings constructed from the specified lhs and rhs arguments, i.e., basic_string(lhs).append(rhs). The allocator of the returned string is determined per the rules in P1165 (https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1165r1.html). Note that overloads that accept rvalue references are implemented for C++11 and later only.
