Then the manual should be corrected to state that much more explicitly
than it does now. Perhaps it shouldn't even talk about destructive
removal, as that will surely spread confusion. For me "destructive"
means "in-place", and no amount of describing how 'delete' works
internally will ever be able to countermand that. Besides, if all I
need is a quick reminder about the semantics, I'm unlikely to read all
the verbiage, let alone go up to read more under 'delq'. So the most
important facts should be right there at the beginning, not hidden
away under "note that" etc.
