Re: [Haskell-cafe] Adding Content-Addressable Storage to GHC

Great idea! We already have syntax for package imports: ``` import "bytestring" Data.ByteString ``` Source plugin could probably pull and build package by CAS: ``` import "CAS_6ffeacff768590" Data.ByteString ``` That would reuse existing syntax without confusion. And without inconvenience of having to import expressions one by one. Or declaring their types. One could even add CAS hashes to Hackage db. Probably the source plugin can add `-package` parameters with GHC_OPTIONS? On the expression side, it seems easy to use Generics to derive hashable for `Exp`, given a *particular compiler version*. Warning is, that one needs to be more careful when the `Exp`ression type changes. -- Cheers Michal
