Hello Cafe,

I am pleased to announce the first release of Rlang-QQ. You can find
it at <http://hackage.haskell.org/package/Rlang-QQ->.

The package provides a quasiquoter which makes it easier to call R
(<http://www.r-project.org/>) using values calculated with GHC.
Variables in quasiquoter prefixed with hs_ lead to the corresponding
haskell variable being made available to R (provided there is an
instance to marshal values of that type). In other words, `hs_foo' in
the quasiquote will start off as whatever `foo' is on the haskell
side. For now no attempt is made to translate anything on the R side
back to haskell.
