What am I doing wrong here, is it not possible to use ternery inside Triple?

return Triple((adults > 0 ? adults : null), (children > 0 ? children : null), (infants > 0 ? infants : null))

Kotlin does not have the "ternary operator". Use an if expression instead:

Triple(if adults > 0 adults else null, ...

Thanks, takeIf is definitely better.
