Ok, that is good to know. Thanks for the quick response

With a little guidance I'd happily look at it now if that is deemed  
wise given the current plans for Clozure and the bridge.

I am actually using it to acclimate myself to Clozure and its Cocoa  
interface as I am hoping to port an Object-C++/Cocoa/OpenGL  
application to CL over the next few months and it seems the most  
promising route to take.

Thank again.
