Can't do what you want specifically, but you can stuff everything into
a dictionary and pass it around.
I'm not 100% sure I understand what you want to accomplish, but I
hope this helps. Have digest return a dictionary of tokens/values.
tokenDict=digest("FOR", "IDENT", "EQ", "INTVAL", "COLON")
then refer to things as tokenDict['ident'], tokenDict['start']
