Re: globals (_locals)

["Nick Trout" <nick@...>]

This sounds like a great solution. - No flags, no switches, no pragmas.
Good. Probably better than Python as you dont get misnamed locals.

If you have no globals to reference would you do:

  function f()    -- OK
    global      -- turns on dmode (only inside f)
    c = 1       -- ERROR; c is undeclared
  end

This would be a redundant question if you inherited the dmode.

  a = 3;  -- OK, default is declaration mode (dmode) off

  function f()    -- OK
    global b        -- turns on dmode (only inside f)
    b = 1
    c = 1       -- ERROR; c is undeclared
  end

  x = 4;      -- OK; out of scope of "global b", so back to dmode off

On the other hand, if the chunk starts with "global", then everything
in it will inherit the dmode on.
