    -N, --resolve-names     Resolve names using NodeVisitor\NameResolver
    -c, --with-column-info  Show column-numbers for errors (if available)

    -r, --with-recovery     Use parsing with error recovery
    -h, --help              Display this page

Example:

Dumps nodes, pretty prints them, then resolves names and dumps them again.
