I would prefer the enable_if constraint to be on the return type, so
there is only one template parameter:
template <typename _Tp>
enable_if_t<is_convertible_v<const _Tp&, __sv_type>, basic_string&>
append(const _Tp& __svt,
size_type __pos, size_type __n = npos)
However these function templates appear to have a design problem, see
PR 77264.
