@arekolek There's this issue that's WIP, it's also about smart casts and inline functions: https://youtrack.jetbrains.com/issueMobile/KT-14397

[arekolek]

Thanks. I was thinking about things like foo.takeIf { it is Foo } for those cases where foo is a “property with an open or custom getter”

[arekolek]

But I can write foo.let { if (it is Foo) } which is not too bad

[lovis]

write your own: inline fun <reified T> Any.takeIfInstance() = this.takeIf { it is T } as? T should work
call it val astring = myObj.takeIfInstance<String>()

[karelpeeters]

Hmm that rings a bell, doesn't something like that exists already?

[karelpeeters]

Maybe for filtering collections.

[lovis]

yes there is filterIsInstance and mapIsInstance (must have dreamt about the last one)

[ilya.gorbunov]

just use foo as? Foo
