Hmm. I'm deeply suspicious of `StaticKey`. It plays no role in our
#11526: unsafeLookupStaticPtr should not live in IO -------------------------------------+------------------------------------- Reporter: edsko | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.1 Component: Core Libraries | Version: 8.0.1-rc1 Resolution: | Keywords: 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 mboes): Replying to [comment:5 simonpj]: plan of record [wiki:StaticPointers]. FTR the reason we have StaticKey (i.e. just Fingerprint, nothing new) is to avoid hardcoding encoding/decoding of static pointers in the compiler. Encoding/decoding is `binary`'s business, or any other package. Patrick Mayer in particular was keen to minimize message size in his use cases to the bare minimum, say by maintaining himself a perfect hash for fingerprints and hence sending only a small integer across the wire. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11526#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
