Parser
This includes the parser and generated ast.
Parslet is really great in that it:
- does not generate code but instean gives a clean dsl to define a grammar
- uses ruby modules so one can split the grammars up
- has a seperate tranform stage to generate an ast layer
Especially the last point is great. Since it is seperate it does not clutter up the actual grammar. And it can generate a layer that has no links to the actual parser anymore, thus saving/automating a complete tranformation process.
