Interpret haskell within haskell.

[David Sankel]

I was wondering if there is any project that aims to
interpret haskell within haskell.

Is it feasable that a program can import a user's .hs
file that has something like:

greeting :: String
greeting = "Something"

port :: Int
port = 32 + 33

And the program can parse and execute the user's
function.

I'm looking for something similar to the eval command
in Python.

Thanks,
