template-haskell's Language.Haskell.Syntax module should be Trustworthy
The reason why this module isn't inferred safe is that it uses unsafePerformIO to create a global IORef.
From a SafeHaskell perspective, this module isn't very useful in itself, but its unsafety prevents other modules that import it to provide class instances from being inferred as safe. A concrete example is https://hackage.haskell.org/package/exceptions-0.8.3/docs/src/Control-Monad-Catch.html#line-186
