Re: question on local vs nonlocal

[Andrea <andrea.l.vitali@...>]

Oh now it's clear! thank you very much!! This is the kind of examples and justification I was looking for!

function make_counter()

  local x = 1

  return function() x = x + 1; return x; end

end

 

function read()

  return x

end

function write()

  x = 1

end

Since neither of these have any declarations, I would hope that they would behave the same way with respect to the x variable -- either both local (which makes read() an error) or both global, but in a language with "nonlocal" then read() is global while write() is local.
