[ruby-core:67808] [ruby-trunk - Feature #4824] Provide method Kernel#executed?

Issue #4824 has been updated by Nobuyoshi Nakada.

Description updated

My proposal was `__FILE__.main?`, not `FILE.main?`.
Just you're confused by markdown.

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.
