For a very up-to-date document on what External Core looks like,
check out cvs, or go to:
    http://cvs.haskell.org/cgi-bin/cvsweb.cgi/fptools/

and look at:
    fptools/ghc/compiler/parser/ParserCore.y
or:
    fptools/ghc/compiler/coreSyn/PprExternalCore.lhs
also:
    fptools/ghc/utils/ext-core/*

I found these quite useful.
