+1 (a no-brainer, in my opinion) --- although you can get rid of unsetEnv
if you make setEnv take a "Maybe String", which might be better. Ultimately
though, who cares what color the bike shed is painted :)

Hi, setting environment variables is possible on both POSIX and Windows systems. Currently this functionally is missing from System.Environment; the "unix" package provides an implementation for POSIX systems.
I propose to add setEnv/unsetEnv to System.Environment, so that it is easier to write applications that behave the same on POSIX and Windows systems.
I implemented both in a way, so that they behave exactly the same on POSIX and Windows (modulo case sensitivity on Windows).
For now I prepared a standalone implementation [1] and corresponding tests [2]. That implementation depends on the "unix" package. If the proposal is accepted, I will prepare a patch against "base" that includes the relevant code from "unix".
Discussion Period: 2 Weeks
Cheers, Simon
