[antlr-interest] Possible Antlr defect?

[Terence Parr]

Hi. Unfortunately, this is not exactly a bug, just undesirable.  You  
can *add*token definitions to the ones that have already been  
imported.  There are many imaginary tokens you need when doing tree  
construction.  If ANTLR were to warn you upon every new imaginary  
token, it would be a drag.  Perhaps we need an option to warn you of  
these things, or better yet, something in ANTLRWorks that would warn  
you. :)
