I like the general idea of the patch.
Ideally, we should avoid introduction of yet another flag for this.
I understand the concern about memory consumption, and I share it.
But, it would be great we could limit that without introducing
new flags -- because it seems the flags would be there only to
expose implementation inefficiency, not fundamental user-level
functionality.
I suspect that for many reasonably well written C++ programs, all those
loci are the same. Very few would have all three loci (and actually there
is at least a fourth) different. I would suggest exploring functional
interface where there are different location implementations, corresponding
to the different sensible combinations of location kind. This way, only
tokens that are actually macro expanded or created through macro
expansion or strnigification get additional necessary slots.
