Before this commit, questionable optimization existed which unwrapped string interpolating call with single argument to this argument. However, this led to source element loss and the necessity of sub-hacks. In this commit we dropped this optimization (anyway user can remove this single-expression string template in code if needed) to keep source elements intact.
