The first implementation #3353 was incomplete, so sadly it had introduced many IFTI regressions - 12403, 13026, 13180, 13223, and 13294. Eventually I noticed that using typeMerge was wrong. It was the biggest root the regressions. And, the enhancement 13127 was pointless change. Now it is mostly reverted. https://github.com/D-Programming-Language/dmd/commit/a7786fadb495a19364da4aa564e6cccf37224750 Merge pull request #3896 from 9rnsr/fix13294 [REG2.066] Issue 13294 - [IFTI] IFTI fails or works incorrectly for function with const and mutable `ref` parameters of most types --
