Dear committee,
In
#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
