You probably need to dive down into the Scanner. For example if you used
period and modified Scanner>>xLetter to not terminate the scan if it sees a
period followed by a capital letter you'll likely be able to parse e.g.
BB5a.Bank as a single token. If you look at the xLetter method you'll see
it already tests self allowUnderscoreSelectors to accept underscores.
Ah, so an alternative would be to make sure the allowUnderscoreSelecctors
preference is set and use underscore as your separator.
