Not a problem but a mere curiosity; is there any more 'first class' way of writing { it } where for a single parameter lambda that merely pipes-through its input value?

[ephemient]

hmm. you could define a

fun <T> identity(): (T) -> T = { it }

similar to Java's Function.identity(), but I don't think it would be any easier to use than { it }

[darkmoon_uk]

I agree it would be pointlessly obfuscating to define a new function for it.

@darkmoon_uk I do not understand the question, can you give an example?

mine: borrowing from the brief amount of lectures on Categorical notation i caught.

/**right identity*/
inline val <reified T> T.`⟲`
    get() = { this }

1.`⟲`
"const".`⟲`
(args[1]).`⟲`

what am i looking at

[jimn]

: () -> T

[jimn]

sometimes you don't want to commit to a feature being mutable or immutable in your design, so you can use ()->T instead
