I was also asked to create a .C interface, which to me has the only difference that one needs to preallocate the result. But the same is easy to implement by pre-allocating an R variable and passing it as an argument with NULL return. > I'd like a configurable extension > [including .m] and the ability to prepend functions as code.

However, what I would consider reasonable is to have such an inline interface to more than just C and C++. There is something for Ruby I think, but one could think of generalizing it somehow.
