Yeah I just want the compiler to catch all my mistake for me, and this seemed like a real easy case for the compiler to check that for me

@Trevor What about logins[0], should this also return nullable type Login? or throw checked exception as list can be empty? 🙂

[Trevor]

Ah! You got me @Pavlo Liapota, from that perspective you're right, I would expect an exception. so logins[0]? would be the equivalent of firstOrNull?

[Pavlo Liapota]

Such construction logins[0]? will be confusing when used together with operator ?.

[Pavlo Liapota]

Imagine logins[0]?.name, is it logins[0]? . name or logins[0] ?. name
