I agree that this isn’t usually a good suggestion. It is available as a
refactoring for when you might need an iterator, but by no means should the IDE
“warn” about it. I think that is the current behaviour though. The line is
not marked with a hint lightbulb unless I put the cursor on that line. So it’s
not like it shows in the gutter as a warning like you would get for an unused
private function or similar.
It appears to be the hint “Expand Enhanced For Loop” that you will find under
“Suggestions” in the editor Hints panel.
When I turn that off the”expand” hint, the suggestion changes to “Can use
functional operations” which coverts the loop to this.dictionart.forEach(word
-> {...});
