I have found a bug in Data.Version. The expression:

readP_to_S parseVersion "1.0"

produces:

[(Version {versionBranch = [1], versionTags = []},".0"),(Version {versionBranch= [1,0], versionTags = []},"")]

With other words the parser is ambiguous.

It's no more ambiguous than readP_to_S (many1 (satisfy isDigit)) "1234" [("1","234"),("12","34"),("123","4"),("1234","")] It just needs to be used in context.
