Scanner

The scanner returns two kinds of objects: tokens in the input program, or the end-of-file delimiter. The latter is returned as an zodiac:eof struct:

eof (location)

while all other objects returned by the scanner are a sub-type of zodiac:scanned:

scanned : zodiac ()

In turn, zodiac:scanned has one sub-type: zodiac:token, which is the most specific type of all the objects returned by the scanner.

token : scanned (object type)

The object and type fields will be documented later.
