Good catch, thanks Adela!  Installed.

Note that these guys are critical in the case of C and C++ because of macros.  
So if you define a token named EOF for instance, you'll get a clash with the 
EOF macro.  That's why it is important there to be able to "move away" from 
dangerous names.

In D and Java, since the symbol and token kinds are "scoped", there's no risk 
of collision, so it should not be so important.  But it does give us some 
consistency.

Cheers!
