Subject: [ruby-core:36906] [Ruby 1.9 - Feature #4824] Provide method Kernel#executed?


Issue #4824 has been updated by Jan Lelis.


I'd still prefer a Kernel method - It's about better readability, isn't it? My favourites:

directly_executed?
standalone?

If it should be some kind of keyword, I can't see any serious issue against the __MAIN__ solution. It's true in the "main" file, false in all others and

if __MAIN__

looks OK.

Feature #4824: Provide method Kernel#executed?

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

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

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

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

or

main() if executed?

This addition would not break any existent behaviour.
