different versions will be considered to have *different* types (albeit with the same name) On Mon, Oct 20, 2014 at 2:27 PM, Christopher Allen wrote:

Sorry to bother everybody, but where is this documented? What happens if incompatible versions pass data between each other?

I read recently that Rust has some sort of symbol-mangling in place to allow multiple versions of the same library to co-exist within a single build.

How feasible would it be to add this feature to GHC? At a first glance it seems like it would help substantially.

GHC already has this feature (and in 7.10, it will be upgraded to allow multiple instances of the same version of a library, but with different dependencies). The problem here is that Cabal doesn't understand how to put dependencies together like this.
