About underscores in type arguments / partial type arguments

[Tesla Zhang]

Hi all,

Is there any discussion related to partially specified type arguments (which are left for inference)? I just saw that Kotlin 1.7 added support for that. It would be nice if Java can have that too: https://kotlinlang.org/docs/whatsnew17.html#underscore-operator-for-type-arguments


The demonstration of the feature in the above document is also applicable to Java.


Best regards,
Tesla
