Why doesn’t the T of

Comparator<T>

have input variance? I was trying to assign a Collator (which for some reason is a

Comparator<Object>

in Java) to

Comparator<String>

. Is it because it’s simply a typealias?

exactly

although it being a typealias is just a platform concern-- it does feel like it should be <in T> in stdlib-common. I can work around with

Comparator(collator::compare)

though

The problem is that

Comparator<T>

is defined in the java stdlib, so kotlin is unable to change that
