I've never seen anyone write multiple-parameter functions without 
commas...and if I did, I would tell them they forgot a comma. I don't 
think that is a serious problem...but if you really want to do that, you 
can just allow a comma and use the same technique to check the Token_Id 
of the next token to see if it was a float, unget it, and use 
Parse_Float() if it was a float token.
