You've misunderstood. You still need the local statement to make a local
variable. Because of "lexical scoping" you have a lot more options on how
local a "local" is, but Lua still defaults to global unless you use the
local statement. For instance...
Foo = 1
Bar = function() do
local Foo = 5
do
local Foo = 7 -- I <think> this is illegal in Lua 4
return Foo
end
end
contains 3 separate Foo's, while ...
Foo = 1
Bar = function() do
Foo = 5
do
Foo = 7
return Foo
end
end
contains only 1 global Foo.
