What will be the value of …

Given that the following code has been run:

if false
  foo = 'test'
end

What will be the value of:

• defined? foo
• defined? bar

defined? foo
#=> "local-variable"
defined? bar
#=> nil

foo has been at least read by the interpreter, therefore it is defined and assigned a nil value. However, since bar has never been written, it was never defined in the first place.
