Sort of.  See http://www.haskell.org/haskellwiki/GHC/As_a_library; in
particular, http://www.haskell.org/ghc/docs/latest/html/libraries/ghc/InteractiveEval.html
is probably of interest.  I don't know how much of GHCi you'd have to
reimplement, though — the library is there, and does everything GHCi
does, but I don't think it includes the REPL per se.  Looks to me like
you'd need to implement your own parser for ":"-commands and "import".
