A modern programming language that makes developers happier.

Is there a way to instantiate an object while setting some properties on it? As an expression like:
```
val a = Some() { b = "value" }
```
Or do I need multiple lines for that

if the properties aren’t in the primary constructor and are public `var`s (_and_ you don’t control this class), you could just `val a = Some().apply { b = "value" }`

given the caveats I mentioned I don’t know that it’ll necessarily solve the problem

but if works, great

the constructor approach lets you set properties that are `val`s (assuming you have them defined in the primary ctor) and allow the parameters to be private instead

it’s all val. I don’t have an explicit contructor. The class is written in Java

If `Some` is Java, then `apply` is the way to go.
