// println is a simple yet powerful builtin function.
// It can print anything: strings, numbers, arrays, maps, structs.
println(1) // "1"
println('hi') // "hi"
println([1,2,3]) // "[1, 2, 3]"
// Printing structs coming soon
println(User{name:'Bob', age:20}) // "User{name:'Bob', age:20}"
// If you want to define a custom print value for your type, simply define a .str() string method.
// If you don't want to print a newline, use print() instead.
