To debug / reporting purpose, before a refactor, we need to print the current file name in a rule refactor method.
Here we do a LOT of highly specific filtering, so I need to dump filenames where filter passes BEFORE doing any changes, so rector reporting will not output nothing.
Can a rector rule access current parsed file name?

Also, in the
refactormethod we can also see line of current node
