Yes, I want camel-case above.

And this is the part that I object to. I have quite a number of  
keywords and I don't want to have a bunch of if statements or have a  
hash table mapping lowercase to camel case. This would mean having to  
track the parser (camel case) version in two places: the lexer and the  
parser.

What I want is to extend Camlp4.Struct.Grammar.Static with a custom  
version of Make that applies String.lowercase before giving the string  
to 'using' to be inserted into the keywords table.
