But in Perl 5 to "navigate" complex structures one needs ad-hoc solutions. I wonder if something is planned in Perl 6 as a means to do that through a syntactically convenient construct with ad-hoc-isms pluggable in in the form of suitable hooks (e.g. .on_node( { code; ... } ), etc.) that would work in most cases.


I've got some Perl 5 code that tries to do this:

Simple things are fine but path or relationship based transformations
turn into a mess.
