The RB AST is missing some information. E.g. it tells you "there is a variable a", but not
if it's a temp, ivar or what kind of literal variable. (for example).

So it's an AST without semantic analysis. PetitAnalyzer adds this semantic analysis phase
and annotates the AST.
(It's therefore very similar and needs to be merged with the semantic analysis of Opal...)

The package PetitAnalyzer adds reflective facilities (querying,
rewriting, tranformation) to PetitParser. PetitAnalyzer is not
required to write and execute grammers. Typically you only need to
load the package PetitParser. I haven't written the configuration
myself, so I don't know how it is setup.

Ok now I was wondering why we need that in petitParser core in the configuration.

No, PetitParser has nothing to do with the AST package of RB. What you
are talking about is AST-Analyzer, and that's in the RB repository.
