// FOR FOLKS STUMBLING ACROSS THIS LATER
// This is an example of code that allows us to create arrays by calling a function a fixed number of times.
// In my example below I'm just sending in 5 because I don't want to cloud the benchmark with generating 
// a random number or similar, but with this change you can replace the 5 with `Int.random(in: 1...10)` to
// get an array of random numbers.
//
// HERE'S THE STDLIB ADDITION TO MAKE THIS WORK:
//  @inlinable
//  @_semantics("array.init")
