There will probably be one.  And Kevin Kenny will know it. :)

I don't think we can find any character that is readily available on most
keyboards that we can guarantee won't be used as part of an address
number.  Some people even objected to | as being hard to type!

The only way I can see of handling it is to split an interpolated address
range into prefix, range start, suffix, and increment, each with its
own namespaced tag.  Prefix and suffix are both optional.  Increment
might be optional if we can agree on a default.  By making them
each tags we don't need to worry about avoiding/escaping
certain characters.

For Queens, prefix would be something like "122-", no suffix.

It would be clunky to enter as raw tags but editors might manage to
simplify matters in their GUI.
