It could not sensibly be implemented. Every Map implementation would have to implement filter.

[artem_zin]

Something like

inline fun T.filter<reified T : Map<X>>() {
  when (this) {
    is HashMap -> HashMap(result)
  }
}

Wouldn’t work for custom types yeah

[diesieben07]

And it's also extremely ugly if you can just do map.filterTo(HashMap()) { }.

[artem_zin]

yep, I agree, just saying 🙂 I like that it returns Map tbh

[artem_zin]

less code relies on implementation

[diesieben07]

Yep, which is good.
