Remote GHCi

[Richard Eisenberg]

How does this interact with typechecker plugins? I assume they would still happen in GHC's process.

I've also been thinking about designing and implementing a mechanisms where programmers could specify custom pretty-printers for their types, and GHC would use these pretty-printers in error messages. This action would also probably need to be in the same process.

Would either of these ideas be affected? My guess is "no", because we should be able to be selective in what gets farmed out to the second process and what stays locally.

It turns out this has quite a few benefits, and would let us kill some of the really awkward hacks we have in GHC to work around problems that arise because we're running interpreted code and the compiler on the same runtime.
