Apparently that is "lexing", and parsing is making sure the tokens are in the allowed order
Yes. I am aware of that academical fine distinction. It is all fine and dandy in a nice, theoretical world of white-space delimited, single character tokens, but it doesn't cut it in the real world as far as I'm concerned.
In many -- arguably, even 'most' -- cases, it in not just a hell of a lot easier to work out where the next token ends if you know what (alternatives) you are expecting, it can be impossible to do so without said information.
And that means that the hand-written "lexer" you need to write in order to use a Marpa parser, has to effectively replicate the state machine that Marpa constructs.
At which point, what purpose does the parser serve?
