I would say this is one of the greatest advantages of VH, don't know if it is
the main one, but it surely is an advantage. I wonder how VH achieves that.
I imagine it manages to run GHC (it uses GHC, right?) inside the .Net VM
or at least access it through some programmatic interface using some kind
of native/VM data conversion. GHC code (and not VH code) do the
typechecking/compilation tricks. Is that right?

Eclipse is Java and I am pretty sure we can do something similar with it
and we actually did something like the second approach prior to version
0.9.1, but just for source code parsing. What do we need for that?
