Hi, how can i make an universal comporator in kotlin?

fun<T : Comparable<T>, K> comparePairByFirst() : Comparator<Pair<T, K>>  = Comparator { p1, p2 -> p1.first.compareTo(p2.first) }

I have this code and it works, but creates a new similar comparator every use. I think it is bad. How can I make it better?

How i can "this" method in inline functions? I want to get that class to log it.

Is it possible to write universal comparator for all cases?

[Eugen Martynov]

Can you share number of your real cases and maybe it is possible to write something generic for your subset of all cases

I need to use it in generic classes

Tha answers:
1. inline it
2. fun<refiend T> foo() { t::class... }
