word = r'[A-Za-z][A-Za-z0-9]*'
//word = ignore_keywords r'[A-Za-z][A-Za-z0-9]*'
name = word (NAME_GLUE word)* // One word or a sequence of delimited words (name used for most model elements)

if you attach the negative lookahead to WORD rather then name, it will catch the keywords AS words. This way you do not have to worry about white space.

I have this working in java and have checked that python also has the same negative lookahead syntax.

//Here is word as allowed_word with the keyword exclusion.
allowed_word = r'(?!(true|false|and|or|me|its|not))[A-Za-z][A-Za-z0-9]*'

// and then name would still be
name = allowedword (NAME_GLUE allowedword)*

Thanks! Yeah, I knew there was trouble there and wasn't super happy with my 'solution'
