I am not entirely convinced that this assessment of the relative difficulty of these options is also true for developers outside the R core group.

But, here's my list of requirements. I know that some of these have been requested on r-devel before. I'd appreciate, if you can help me with at least some:

On the level of plain R code: I am very certain that the customizations that I am doing are perfectly harmless, because it's pretty trivial stuff. You don't have to trust me on that. And of course not any more than you trust the rest of any other person's work, in the first place.

Of course, if what I am doing is "illegal" because it steps on the compiler's turf, then my assumptions do not hold, indeed. That's what I'm worried about.
