👋 Hi all, new to Kotlin and I'm having trouble understanding why the -> is used to specify return types in some cases but not others (e.g. : is used in fun). Is there a reason for this perceived inconsistency?

[karelpeeters]

Where is -> used for return types? It's used in lambdas for the return value.

@karelpeeters it is used to indicate the return type of a function type: var f : (Int) -> Int = ...
It's the same as in many functional programming languages, but besides that I don't really know the reason. Always seemed more natural to me

[karelpeeters]

Ah right, forgot that one. Maybe that's because f: (Int) : Int is a lot more difficult to read?
