Re: Another option for closing variables

[Sergey Kovalev <kovserg33@...>]

I found the way to do it in lua without preprocessing. But only in 5.4.
There is 4-th parameter in for loop introduced in lua 5.4 so
now it look like:

require "scope54" --
https://raw.githubusercontent.com/kov-serg/lua-aux/master/scope54.lua

for auto,defer in scope() do
  defer(function() print"defer" end)
  local f=auto(io.close){ io.open "scope54.lua"}
  print(f:read())
end

I think this is enough readable and looks nice.
