Which are just names for integer values, last time I looked. The type of 
a function parameter would be int. And even if that's not the case, 
experienced users are accustomed to doing it this way from the days 
before it had them. And even newer users are accustomed to seeing it 
done this way in the code they've been exposed to. And even if that's 
not the case, C/++, emphasizing ease of writing over ease of reading, 
induces a mindset in the user of "why bother typing this enumeration 
definition and using it when I can just say int?" All of these are 
symptoms of "C/++ thinking".
