Which langugage extensions are implied by Haskell2010 in ghc?

I don't know why I'm having trouble finding the docs for this, but which extensions are implied by:

{-# LANGUAGE Haskell2010 #-}

I'm mostly just concerned with how ghc handles this, but I assume this is part of the standard.

From the very last section of the Haskell 2010 report, I believe this is what you are looking for (emphasis mine):

Haskell 2010 implementations that support the LANGUAGE pragma are required to support

{-# LANGUAGE Haskell2010 #-}

Those implementations are also encouraged to support the following named language features:

PatternGuards, NoNPlusKPatterns, RelaxedPolyRec,  
EmptyDataDecls, ForeignFunctionInterface

These are the named language extensions supported by some pre-Haskell 2010 implementations, that have been integrated into this report.
