Calling function in a function

Is there to store a function in a variable and call it inside a function?

something like this…

local function foo(x, y, z)
  if x == y then
	z
  end
end
local function anotherFoo()
  print("equal")
end
foo(1, 1, anotherFoo)

Split into new topic.

Change to z() inside that if statement.

Another thing you can do is define functions inside of functions.

local function printResult()
  local function getResult()
	return "This is the result..."
  end
  print(getResult())
end

That is probably not exactly what you want, but I thought it might belong in the same category.
