Get rid of LALRPOP

[pveentjer]

Unlike Pest, LALRPOP has nice error messages.

But its default behavior like eating up comments and line feeds, very weak documentation and clunky behavior around error handling, make it a very painful parser generator to use.

So probably get rid of it and look for something better.
