Hi
I'm not sure offhand why just doing Read/Show wouldn't work or didn't occur to us; is there a reason why that wouldn't be straightforward?
Talking to Matt, the only thing is that currently Show is used for the pretty printed version. Adding a new Ppr class and using that shouldn't be that hard, then you can add the standard deriving Read/Show. Read has rather bad performance, but the advantage of immediately available and very little work might outweigh that.

If you do go down the Read/Show route then a copy of whatever file defines the data type in a standalone library would be all that's needed - possibly with the pretty printer, but that's not essential for people who just want to consume Core.
