Andre Pang is a master student of Manuel Chakravarty. He made a binding
to Cocoa/Objective C using template Haskell. I have just talked with
him,
maybe you can find his thesis using the above information.
(or maybe one of them reacts to this email :-)

I have described the inheritance trick in, hmm, I think in
"calling hell from heaven and heaven from hell"  
http://www.cs.uu.nl/~daan/pubs.html

I am currently working on functional pearl though that describes
everything you can do with phantom types (like relational expressions)
from scratch.

> Do you model multiple inheritance someway? 

No :-)  It is possible though but makes things more complex.

> Does wxwin use multiple inheritance?

Just two (non-essential) classes use this, so I could get
away with just modeling single inheritance.

Cheers,
 Daan.
