// Higher-order function: apply
// Demonstrates passing functions as parameters

fun apply(f, x) {
    f(x)
}

fun double(n) {
    n * 2
}

fun square(n) {
    n * n
}

fun greet(name) {
    println("Hello, " + name)
}

// Using apply with different functions
let result1 = apply(double, 5)
println("double(5) = " + result1)

let result2 = apply(square, 4)
println("square(4) = " + result2)

// This should work but currently fails in v1.17.0
// because function parameters are typed as String
apply(greet, "World")
