another question: 1. I have a `var map: Map<K,...

another question:
1. I have a var map: Map<K,V>? = null class property
2. I do not (or can not) use delegates.lazy for whatever reason

Is there some idiomatic way to say:

if(map == null) { map = mutableMapOf() }
map.doSomething()

or is this the same as with java? I know I could use apply/let stuff here, but dunno if this is the way
