{{code|lang=lua|Buffer .. value}}

{{code|lang=lua|value .. Buffer}}

Any non-table <code>value</code> may be joined a Buffer object with the concatenation operator {{code|lang=lua|..}} without error.

With the exception of Element-Buffers (which are a special case), the op passes each object, ordered left-to-right, to {{luaself|:_}} which inserts [[#valid|valid]]ated items in a new table, which this returns through {{luaref|table.concat||y}}.

Concatenating an [[#valid|invalid]] ''value'' and a Buffer has generally the same effect as {{luaref|tostring|args=Buffer}} unless such involves:
* the Buffer-nil object {{--}} which produces an empty string (instead of nil)
* Element-Buffer objects {{--}} which returns the string of the parent Buffer-HTML{{see|#for Element-Buffer objects}}
