Hi there. Is it possible to write a function, that accepts a function with any number of arguments, of any kind, and execute it? The following works, but only for lambda functions

fun <R>myFunc(block: () -> R): R
{
    println("starting)
    try
    {
        return block()
    }
    finally
    {
        println("end")
    }
}

As in the example above, I would like to do some things before the functions run, and some things after. An example would be to measure the execution time. Appreciate any help!

How do you expect to call the function if you don't know what to give it?

Here's what is in the standard library for measuring execution time. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.time/measure-time.html

You'll notice it takes a Lambda, and returns Unit.

The expectation is all your code would be in the lambda, including any function calls.

As per above, there isn't a way to do what you're asking, as there's no way to know what to pass to the function.
