The value of b is the "main" function of the chunk
       
     1	function a()
     2	  print(1)
     3	  print(2)
     4	end

This main function only has *two* executable instructions:
	- an assigment to a global variable 'a' on line 1
	- an implicit return after line 4

In other words, the main function is essentially this:
	a = function ()
	 ...
	end return

Hence the list of active lines you see.
