[Haskell-cafe] Haskell -> .NET

I think Sigbjorn's binding (http://haskell.forkio.com/dotnet/
<http://haskell.forkio.com/dotnet/>  as linked below) is the most
complete and likely to work, but it's still just a binding not a
compiler backend.

There was in fact another attempt as well, Salsa:

This showed quite a bit of promise but unfortunately was not more than
just an experiment.

	Yes, but interop only touches the surface of what is possible.
	When a Haskell compiler could create IL code, it would be
possible to
	use the generated code inside a sandbox, e.g. to be used on the
web as
	loadable Silverlight code.
	Of course the same could be said about other virtual machines,
such as
	Flash or Java, but I don't know about the tail call issue here.
	I guess for now F# would be the best option, but it would be
	if Haskell compilers could have more backends.
	I realize this is a very big undertaking, and has been mentioned
	before, but it doesn't hurt to refresh the cache lines once in a
	while, so maybe some bright student picks this up and hacks
	something cool during the summer :)
