also can you conceive of a possibility where brackets could and should be omitted? i'm thinking things like 1 line lambda functions, e.g.

list.any it.hasFoo

Doesn’t

infix

already allow for that?

i suppose it does? i've only used infix with traditional functions, not higher order ones.

There’s not really any need for infix with a higher order function parameter. they result in pretty much the same thing

infix fun A.apply(configure: A.() -> Unit): A {
    configure()
    return this
}
A() apply { doSomething() }

vs

fun A.apply(configure: A.() -> Unit): A {
    configure()
    return this
}
A().apply { doSomething() }

Concerning omitting of brackets, I would take the same position as no-bracket

if

statements in that they should be avoided and have brackets unless it’s used as an expression ie,

val a = if (b) "was true" else "was false"

it.hasFoo

is a bit ambiguous though and would probably be better expressed as

list.any(T::hasFoo)

instead of adopting a no-bracket lambda expression
