====Buffer:_2====
{{luaself|:_2|args=name, save|args2='new_G', ...}}

This returns the value indexed at key <code>name</code> in the global table. If it does not exist, this forwards both arguments to {{luaself|:_G}} and returns the saved value (which may be itself).

In other words, {{luaself|:_2|args=name, save}} is roughly equivalent to {{code|lang=lua|1=_G[name] = _G[name] or save or save==nil and Buffer}}.

The string {{code|lang=lua|'new_G'}} will return the Module:Buffer local variable <code>[[#new_G|new_G]]</code>, used as a proxy for the global variable _G. Given more than one argument, this forwards arguments to {{luaself|:_R}} to assign another proxy global before returning the (newly-deposed) proxy. This then sets <code>new_G._G</code> to the original _G object for call chaining. (See &sect; chain call in [[#G object|_G object]]).
