class LineNumberHandler
We need to provide a handler that will add the line to the node as it is parsed. TreeBuilder is the “usual” handler, that creates the AST.
Attributes

The handler needs access to the parser in order to call mark

We are only interested in scalars, so here we override the method so that it calls mark and adds the line info to the node.
