No, heuristics are to be avoided.  There's always too many corner cases
for that to be satisfactory, which approx. three hundred previous
completion frameworks that have tried shows...

All untagged commands are presumed to be somewhat generally useful, so
that doesn't limit it much.  :-)

I think I've argued enough against "(declare (modes" as the only tagging
