whats the downside of using lazy delegate?

[wasyl]

pawel.rybicki: Additional object allocation for lazy instance, second field for value, and overhead when getting value - basically what you see here https://github.com/JetBrains/kotlin/blob/master/libraries/stdlib/src/kotlin/util/Lazy.kt

It is also thread safe, so the lock on the field helps with the overhead

[menegatti]

there are different modes, as you can see here https://github.com/JetBrains/kotlin/blob/master/libraries/stdlib/src/kotlin/util/Lazy.kt#L54
