[antlr-interest] No lexer generated

[Sam Harwell]

It should generate the lexer as long as the composite grammar has at least one lesser rule defined directly in it (not imported). You can create a dummy fragment rule for this to keep out from affecting the behavior of your lexer . This is an ANTLR 3 limitation.

So? Is there any reason why ANTLR won't generate a lexer for a combined
grammar?
