I agree that what's said can cause damage. I don't want to cause harm.

In the hope it helps me cause less confusion in future discussions of P6's sort builtin, please consider putting the +* snippet and ST aside for a moment and answering the following questions. Simple yes answers would be ideal. If your answer is no, then elaboration would be helpful.

  1. You posted something that can be seen as a simple coding challenge. That is, a solution either does or does not get the same results as your P5 code. Did you understand enough of the P6 code I posted to conclude it might get the same results?

  2. Did you catch the point that a key extractor closure (eg { ~days(.day-of-week) }), if not explicitly coupled with an arbitrary comparator closure, is automatically coupled with a generated { $^a cmp $^b } comparator closure?

  3. Did you see how { ~days(.day-of-week) }, { ~months(.month) } directly corresponds to substr(scalar localtime($_),0,3), substr(scalar localtime($_),+5,3)?

  4. Did you understand how having two key extractor closures leads to an equivalent of the || construct in your P5 comparator closure?

  5. Did you understand that ~days(*.day-of-week) is shorthand for { ~days(.day-of-week) }?

Thank you for helping me straighten this out.
