I still expect that managing those simply with minor modes will work well enough. While using id-utils or gtags instead of etags can be valuable, we'd probably stick to only one of them at a time. Maybe choose between them automatically, like semantic-symref does (and allows us to do). > and maybe also to use several backends > at the same time (merging the results). If we agree on the OO approach to grouping (or even the list-of-strings approach), merging them automatically would look pretty unsolvable to me. Concatenation would work, though (with the OO approach).
