#570: Native string interpolation syntax (round two)
Dear committee, In #570 <https://github.com/ghc-proposals/ghc-proposals/pull/570>, Brandon Chinn proposes adding native string interpolation syntax to GHC, along the lines of s"a ${x + 1} b", catching up with and even exceeding similar features in popular programming languages. I think this is an important proposal and I recommend that we accept it. Since the previous submission, Brandon settled on a coherent and simple interaction with -XOverloadedStrings. Although the proposed interpolation API seems more ad-hoc than necessary, I did not find a way to simplify it any further. Cheers, Sebastian
Sorry, this was caught in my spam. I support this proposal. I have made some drafting suggestions on GitHub. Committee members: the ball is in your court! RSVP Simon On Mon, 29 Jun 2026 at 12:41, Sebastian Graf <sgraf1337@gmail.com> wrote:

I support the proposal. I wrote https://github.com/ghc-proposals/ghc-proposals/pull/570#issuecomment-4691830... before the proposal was officially submitted, but it still holds. Rodrigo

I too support this proposal. It addresses one of the few pain points that I regularly run into in Haskell. Cheers, Erik Simon Peyton Jones wrote:

I support the proposal. I think string interpolation is rarely the most principled solution any problem, but it is very convenient and Brandon and all contributors have put enough thought into making sure the proposed string interpolation has few sharp edges. Cheers, Jaro
