Who says its a bug? From my understanding, this exception is there on 
purpose, to make it easier to use the DOT_DOT operator in the slice 
expresions:

   foo[1..2] // It would be silly to have to put a space after the 1

At most you could make a case that "1." shouldn't ever parse as float, 
that the decimal part should be required if the dot is present.
