fn main() { age = 21 }

Using Run works perfectly.

But all other examples like Strings, ...

name := 'Bob' println('Hello, $name!') // $is used for string interpolation println(name.len) bobby := name + 'by' // + is used to concatenate strings println(bobby) // "Bobby" println(bobby[1..3]) // "ob" mut s := 'hello ' s += 'world' //+=is used to append to a string println(s) // "hello world"
Will fail because of the lacking "fn main() {}" is not automatically applied.

Solution: Remove the few "fn main() {" from the first documentation examples and automatically add "fn main(){ // CODE// }" to the Javascript that copies the code to the Play section.
