Comment (by bgamari):

 > Is there document for Core?

 The
 [[https://ghc.haskell.org/trac/ghc/wiki/Commentary/Compiler/CoreSynType|GHC
 commentary]] has a number of references. There is also the
 [[https://www.microsoft.com/en-us/research/publication/system-f-with-type-
 equality-coercions/|System FC paper]] although it may be a bit dense to
 start with. The Notes in `compiler/coreSyn/CoreSyn.hs` are also quite
 helpful.
