I really like using '#' as the index separator. It is sometimes
pronounced "number". It hasn't been used before in osm keys (AFAIK),
which is both a blessing (no clash with an existing definition) and a
curse (need to convince everybody to start using that).

'_', '-', and '' (empty string) have the drawback of being mistakable
for something else.

'[]' may appeal to some (it's the same syntax as many programming
languages), but it feels a bit verbose and it can be a pain for
regexps.
