[antlr-interest] Re: Keywords with whitespaces

So if it doesn't match "begin" "sequence" then it is a parsing error.  When
you build your tree you don't need both tokens, just put your own token type
in there.  Call it BEGIN_SEQUENCE if you like.  It's going to be a lot
easier handling this in the parser than in the lexer.

I'm not sure. ANTLR will add word "begin" _AND_ word "sequence" to 
the table of literals but only the sequence "begin" "sequence" is one 
literal and not both single words.
