I would agree with `main` in the following way:

```ruby
# Kernel#main method to be override and only run if __FILE__ == $0
def main
   Foo.bar
end
```

Feature #4824: Provide method Kernel#executed?

----------------------------------------
The current construct to execute main code looks not very elegant:

~~~ruby
if __FILE__ == $0
  my_main()          # call any method or execute any code
end
~~~

With a `Kernel#executed?` method, this would become more elegant:

~~~ruby
if executed?
  #do this
  #do that
  my_main()
end
~~~

or

~~~ruby
main() if executed?
~~~

This addition would not break any existent behaviour.
