Zubin pushed to branch wip/9.14.2-backports at Glasgow Haskell Compiler / GHC Commits: 79d89ade by mangoiv at 2026-07-20T14:46:27+05:30 compiler: refactor error reporting code for ExplicitLevelImports Refactors error reporting code for ExplicitLevelImports to pass in a RdrName and a GlobalReaderElt to be able to report errors that are faithful to the source and to more precisely distinguish between names that are in scope from different qualifications. Fixes #27385 and #26616 (cherry picked from commit 141986e3680a24b76e21a7ad4ce6290a7413c7f5) - - - - - 25faabc5 by mangoiv at 2026-07-20T14:46:27+05:30 compiler: rename ZonkAny to UnusedType and add pretty printing logic ZonkAny is a hard to understand name for users who do not know how the compiler works internally. Additionally, it is confusing that ZonkAny, while being a concrete type *represents* a meta variable, espeically in the compiler output. This patch changes the name of ZonkAny to UnusedType which is closer to its intended semantics and adds special pretty printing logic to display this type in the same fashion the compiler displays meta variables in other places, whenever they leak from the implementation to the user. It also exports the type from ghc-internal:GHC.Internal.Types in order to expose documentation.
