One can dream... Besides nearby variables, we'd also like to know what is the imminent return value. I imagine that's fine for a typical function, and perhaps for inlines too if optimization didn't morph it away. But it's not clear to me how DWARF could help us with the return value from a tail call. If the callee is statically known, then perhaps some indirection to that site, but in general I don't know...
