But why?

[spand]

So plus operator is concat

[arekolek]

plus Returns a list containing all elements of the original collection and then all elements of the given elements sequence.

Yes... I understand how it happend. But it was postfactum, after type inference gave me List<Any> instead of List<List<Int>>. And I'd prefer to know exactly what's happening when I type it simple smile . I'm wondering if better names could have been used.

[ghedeon]

Check this. IDEA is clearly showing the same result type for both methods.

[ghedeon]

Could be a bug in IDE, right? I mean, the type is statically checkable here and it's not List<List<Int>> as it's shown.

[arekolek]

It seems so. It works correctly when you extract variable and use intention action to set explicit type.
