A larger question is where such a feature would fit in the hierarchy of the important and urgent. I understand the sentiment that something seems naturally desirable to a group of folks, but there is no shortage of things to work on and we need to cull the list. -- Andrei

I started this discussion because I want to continue the work on the Objective-C support. Before doing that I would like to first have a good foundation. Taking the decision if the Objective-C support is enabled or not in the makefile (as it does today) is not a good solution in my opinion. Since both LDC and GDC supports cross-compiling (and hopefully DMD as well in the future) I thought it would be a good idea to move the decision to runtime (of the compiler).
