[Haskell-cafe] Language complexity & beginners (Was: New type of ($) operator in GHC 8.0 is problematic)

[Imants Cekusins]

in addition to Takenobu's links, Real World Haskell explains unboxing
and lifting on p.583

just to clarify, for practical use, is it safe to say that "boxed" and
"lifted" are synonyms? you see, term "boxed" is used in other
languages. I assumed "lifting" related to monads. Hence the confusion.
