I'm not sure if the example shows it (I haven't looked at it in a 
while), but this sort of problem requires semantic 
disambiguation.  Specifically, you need to examine the first 
identifier token and figure out whether it's a type or a 
variable.  You should be able to do this since both types and 
variables are required to be declared before they are used.
