hashable doesn't support filepath-1.5, ghc-9.10 will bump filepath to 1.5

hashable doesn't support filepath-1.5 ( #291 (comment) )

ghc-9.10 will bump filepath to 1.5 ( https://gitlab.haskell.org/ghc/ghc/-/milestones/380)

will this create a conflict?

Hitting this build error:

[3 of 7] Compiling Data.Hashable.Class ( src/Data/Hashable/Class.hs, dist/build/Data/Hashable/Class.o, dist/build/Data/Hashable/Class.dyn_o )

src/Data/Hashable/Class.hs:167:1: error: [GHC-87110]
    Could not load module ‘System.OsString.Internal.Types’.
    It is a member of the hidden package ‘os-string-2.0.2’.
    Perhaps you need to add ‘os-string’ to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.

So, at least dependency os-string has to be added, it seems.

It seems that this is not fixed by head.hackage: https://gitlab.haskell.org/ghc/head.hackage/-/issues/100

Possibly be fixed by:

• added os-string flag to cabal file #290
