Re: Say No to global-by-default

Yes, only _ENV looks like hardly readable code.

namespace MyNamespace - more clean

and can look even more readable with:

use MyNamespace

print(a)
fn1()

For me _ENV works too, only some time code in Lua looks like regular expressions, powerful but hard to read :)

You can already do exactly that with _ENV:

MyNamespace = {}
do
   _ENV = MyNamespace
   ...
end
