This is easily solved by making the lexer not allow the "...." token, or "....." token, etc. (maximum 3 dots.) This way you are forced to insert a space there to make your intention clear, and you can never have bugs like that.
I agree that things could be fixed. This is, however, a hack because a lexer is not supposed to operate that way. Lexers are "maximum munch".
So we're looking at a number of problems here. One is that we'd need to change the language in several places to accommodate an ill-conceived feature. Another is that I can't seem to get some very simple points across such as the difference between a token and a non-terminal, in spite of having tried repeatedly and in various forms. Another is that I am becoming suffocated with self-righteousness and therefore am losing goodwill in this thread at an exponentially-increasing rate. Finally, it looks like such discussions necessitate more than a full-time job.
