[Bug] sorting about pkl HOT 4 CLOSED

This is wild! I managed to reproduce. Thanks for the bug report.

I don't think this is a bug.
The documentation of List.sortWith says:

comparator should return true if its first argument comes before its second argument in the sort order, and false otherwise.

So it should be local com = (a, b) -> a > b instead of local com = (a, b) -> a >= b.

I checked Swift's and Scala's sortWith functions, and they have the same requirement. Swift additionally states that the comparator function must be irreflexive.

Either case, I don't think this is any way intended.

FYI,
found the location of the bug.

That indeed looks like a bug. I guess a reflexive comparator function should only give you an unstable/inefficient sort, not a wrong sort.
