Hi all, Proposal 125 is on the topic of making quasiquoters which annotate the type of expression they produce. For example: qq :: TQuasiQuoter Int which would work when used via foo :: Int foo = [qq|| blah ||] but would be a type error (even before expanding the splice) in the context of bar :: String bar = [qq|| blah ||] I'm in favor of this proposal. It's small, a natural extension to typed expressions+quasiquoters, and solves the very real problem of statically verifying literals at compile time. The proposal is here: https://github.com/ghc-proposals/ghc-proposals/pull/125 and my recommendation is: https://github.com/ghc-proposals/ghc-proposals/pull/125#issuecomment-5106120... I have recommend a syntactic change that is *not* present in the original proposal text. It seems unfair to make the proposer jump through more hoops after a year of inactivity on this proposal. As usual, silence will be considered assent! Best, Sandy
