>> I just tried this patch out yesterday. I would like to ask why, if you're going to all this trouble, do you not also include information about the end of each token as well as the start? From a toolbuilder's perspective it would make this patch immensely more useful. Just a couple of examples would be when building Erlang backends for refactoring tools or context sensitive autocompletion in the editor.
