compiled haskell module represented in ghc as a .hi+.o files,
installed libraries as a .a plus a set of .h files (you may find lots
of .hi in your ghc installation)

afaiu, .hi files contains parts f source haskell code in some
partially compiled form. ability to perform inter-module and
inter-library inlining is a key to efficiency of ghc-compiled
programs, specially for polymorphic functions. when you use such
functions as head, you are definitely got them inlined
