#14255: Type-indexed type fingerprints -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Core Libraries | Version: 8.2.1 Resolution: | Keywords: Typeable 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 dfeuer): Whether or not we can reduce the size of the trusted code base, I think this is a good thing to offer. In particular, applications that use deserialized `Dynamic` very heavily, but that ''don't'' use `dynApply` or other reflection-based operations can be much more efficient if they stick to fingerprints instead of full `TypeRep`s. Indexing these fingerprints by type supports a friendly and modern, though necessarily limited, API. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14255#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
