i tried doing let{::loveThePet} but the return end up beign different and could not chain the calls, they were returning a KFunction instead of the result

[Shawn]

{::loveThePet} is a lambda that returns a reference to loveThePet

[Shawn]

let(::loveThePet) invokes let on the receiver object using loveThePet as the function parameter

[Shawn]

they are very different expressions

[Shawn]

let{::loveThePet} would be equivalent to let({ ::loveThePet }) or

val func = { ::loveThePet }
item.let(func)

What you’d be doing, in essence, is passing to .let() a lambda that discards its arguments and simply returns that method reference, which is why you get a signature error and end up with a transform that leaves you with a KFunction

[Shawn]

the requisite expression would therefore look more like this

returnHuman("name")
    .let(::saveAHumanReturningABall)
    .let(::kickTheBallReturningABall)
    .let(::keepTheBallReturnAPet)
    .let(::loveThePet)

[Shawn]

assuming those functions are member declarations and not just local variables

[Shawn]

if they are just local variables, the :: is not needed to qualify based on namespace
