Re: Calling Haskell from Python / C++

Simon Peyton-Jones writes:

If Python uses C's calling convention, it might be easy; just use 'foreign import' and 'foreign export' (see the FFI spec at haskell.org).

I remember reading that the main program, that wants to call Haskell code, would have to be compiled with a special Haskell main() routine, though? Is that true? And if, why is that necessary? -peter
