Following the example from the docs, this works:

array<int> arr = {3,2,1};
arr.sort(function(a,b) { return a < b; });

I would expect the following to work:

bool less(int a, int b) { return a < b; }
...
array<int> arr = {3,2,1};
arr.sort(less);

but instead it errors:

ERROR : No matching signatures to 'array::sort(::less)'
INFORMATION : Candidates are:
INFORMATION : void array::sort(less&in, uint startAt = 0, uint count = uint ( - 1 ))

How do I pass array.sort an existing function instead of an anonymous function? I'm using Angelscript 2.32.0

Okay, now how do I get this to work?

bool weaker(const Info@ &in a, const Info@ &in b) { return a.hp < b.hp; }
array<const Info@> attackableEnemiesByHp() {
    array<const Info@> attackable_enemies = attackableEnemies();
    
    attackable_enemies.sort(weaker); // ERROR No matching signatures
      
    return attackable_enemies;
}

Info is a class representing an entity in the game.
