Are referring to the need for calling a static method on a class that
should be able to be loaded from a nib? In that case have you tried, at
runtime, inspecting the symbol table in the loaded binary and getting
the address to the necessary functions and calling them.

I noted this as well, it creates an insanely amount of code. I also
noted that compiling as a dynamic library reduces the size about 50%.
I've actually been working on my own implementation of an Objective-C/D
bridge based on your blog posts and documentation. I've never released
or announcement anything but I have a project at dsource:
http://dsource.org/projects/dstep . I started this before your bridge
supported DMD because of no support for DMD or Tango and I was not happy
with the GPL license. I also added small enhancements in some places.
I also have ruby scripts (based on bridgesupprt) for automatically
creating bindings with results that are ok but not perfect. I was
thinking about create a tool using Clang and hopefully have a completely
automatic process when creating bindings.
What would you say about working together on an Objective-C/D bridge?
