Accessing functions by name (or something?)

[jwoertink]

Let's say I have a lua file like:

function one()
  print("one")
end

function two()
  print("two")
end

return one, two

Then I add these to the stack:

lua = Lua.load
code = lua.run File.new("./test.lua")

I can do a secondary run lua.run("one()"), but is there a way to gather these functions individually by a name or something?

What I'm looking to do is call them from within Crystal like one.as(Lua::Function).call. Then I can pass in args from Crystal. I know I can do this if I return a single function, but what if I return multiple functions, and I can't guarantee which order they were returned in?
