I noticed that there are massive amount of CPP pragmas to switch code
between GHC and non-GHC (e.g.,
and they are a burden for maintainers. Moreover, the non-GHC part of the
codebase is untested due to the lack of viable alternative compilers (

Therefore I propose to revisit the policy for portability of core
libraries. Portability is not a bad thing, but few people use
other compilers these days. The drag is only likely to increase because
there's no plan (AFAIK) for a new Haskell standard.
