I frequently come across the situation where I want to derive an object from another one and have the choice to write an extension function or an extension property like so:
fun MyClass.foo(): MyOtherClass = ... val MyClass.foo: MyOtherClass get() = ...
The difference on the call site is clear
val a: MyClass = ... a.foo() a.foo
I have a rough understanding that it is a question about action vs state, but in many situation it is not so clear and I can’t keep myself from getting lost in thinking about it, which drives me crazy a bit.
So, what are you strategies/rules/guidelines here? Or maybe you just don’t care?
