Then I agree with Miko, it's not really a problem to explain the unusual cases of C<BETWEEN>, if we already have to explain the (identical) unusual cases of C<LAST>. Thinking about it this weekend, it seems that the concept might be made palatable if it were taught by first reviewing the current behaviour of closures and then explaining that C<LAST> and C<BETWEEN> behave the way they do because they are closures.
