#8441: Allow family instances in an hs-boot file -------------------------------------+------------------------------------- Reporter: goldfire | Owner: ezyang Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: backpack, | TypeFamilies, hs-boot Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ezyang): So, this is actually not so trivial even for Backpack. The problem is that data families turn into a rather delicate constellation of interface declarations, and the way signature merging is written, I have to teach it how to hoover these all up BACK into (deduplciated) FamInsts, so that when I write it out to an interface for the final time, everything is kosher. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8441#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
