Local and Global Variables

[moonfruit <dkmoonfruit@...>]

I am wondering why LUA is be designed like this:

    j = 10     -- global variable

    local i = 1 -- local variable

and not like python:

    global j = 10 -- global variable

    i = 1          -- local variable

I usually forget to add local to variable declaring,

Because nearly all programing language which I used default set variable's scope to local.

Is there someone can tell me why?
